Sutrasthana 2.5 — Añjana (Daily Sauvīrāñjana for the Eyes)

Añjana (Collyrium for the eyes): Sauvīrāñjana is beneficial for the eyes; therefore one should use it daily. The eye is made of tejas (fire/light element), and for that reason it has particular danger from śleṣman (kapha). (5)

Translation: Prof. K.R. Srīkaṇṭha Murthy, Ashtanga Hridayam Vol. I (Sūtrasthāna), Chowkhamba Krishnadas Academy, Varanasi. Verse 5 covers the daily sauvīrāñjana practice; the weekly rasāñjana (Berberis aristata) application follows in verse 6, along with the transition to nāvana (nasal drops), gaṇḍūṣa (mouth gargle), dhūma (herbal smoke), and tāmbūla (betel chewing).

Note: Sauvīrāñjana is stibnite (antimony trisulphide, Sb₂S₃), historically sourced as shining black pebbles from the river beds of the Sauvīra country, a region corresponding to modern Sindh and parts of southern Baluchistan (present-day Pakistan), along the lower Indus. When ground and combined with plant extracts, it becomes the classical eye-salve, the same mineral substrate that produces the Arabic kuḥl, the Persian sormeh, and the South Asian kājal. A critical safety caveat applies to modern commercial products: many kohls sold under this name in 2026 contain galena (lead sulphide) rather than stibnite, and are toxic. See the Modern Application section below.

Verse 5 opens the eye-care segment of the dinacaryā. In six Sanskrit words the verse names a practice, prescribes its frequency, and gives its doctrinal justification. The compression is characteristic of the text, but the density repays careful unpacking: the daily application of collyrium is one of the most continuously practiced of the Āyurvedic morning rituals, still performed today across the Indian subcontinent, the Middle East, and parts of Africa. The reasoning in this verse explains why a tradition that asks nothing else of the eyes asks this of them every morning.

Sauvīrāñjana: what it is

The Sanskrit sauvīra is a geographic adjective. Sauvīra was an ancient country corresponding to modern Sindh and parts of southern Baluchistan along the lower Indus, famous in the classical period for the quality of its mineral exports. The black glittering pebbles found in its river beds were identified by early Āyurvedic physicians as a specific mineral with specific pharmacological properties: stibnite (antimony trisulphide, Sb₂S₃), the naturally occurring ore of antimony. Añjana is the general term for eye-salve or collyrium. Sauvīrāñjana is therefore "the añjana made from Sauvīra stone."

In classical preparation, the stibnite pebbles were finely ground (levigated in mortar with water, sometimes for days), then combined with plant products (rose-water, saffron, camphor, clove, various botanicals in regional variations) to produce a fine powder or paste. The preparation was applied to the inner rim of the lower eyelid (the vartmā), not to the eyeball directly, using a small rod (śalākā) of gold, silver, or a smooth piece of tamarind wood. The ground mineral, when contacting the tear film, distributes across the surface of the eye and along the conjunctival margins. Its effects are at once mechanical (fine abrasive clearing of accumulated mucus), pharmacological (antimony compounds have documented antimicrobial activity), and cosmetic (the black pigment outlines the eye and protects against glare).

The practice is ancient. Egyptian kohl jars have been recovered from burials at Thebes dating to 2000 BCE and earlier, their pigment analyzed by modern spectrometry as galena (lead sulphide) mixed with stibnite, malachite, and organic binders. Mesopotamian medical tablets describe similar preparations. The Sauvīra-sourced antimony pigment was traded along the same routes that carried spices and textiles, and the common vocabulary across Arabic (kuḥl, from which European "alcohol" eventually descends via a centuries-long semantic drift), Persian (sormeh), Urdu (surmā), and Hindi (kājal) all point to a continuous practice-lineage stretching back at least four thousand years.

Cakṣus tejomayam: the eye made of fire

The verse's second line is doctrinal, not technical. It explains why the eye specifically requires this daily attention. Cakṣus tejomayam, "the eye is made of tejas." In Āyurvedic and Sāṃkhya anatomy, each of the five sense organs is mapped to one of the five elements: the ear to ākāśa (space, because sound travels through space), the skin to vāyu (air, because touch is the sensation of contact), the eye to tejas (fire/light, because vision is the perception of light), the tongue to āpaḥ (water, because taste requires moisture), and the nose to pṛthvī (earth, because smell is the sensing of material particles).

This is not metaphor in the tradition's own terms. The eye is understood as literally composed of the tejas element, and its function (the perception of light) is the natural activity of that element expressing itself in the sense-organ form. The pupil is the aperture through which the inner tejas meets the outer light; the retina is the surface where the two forms of tejas interact. The eye's capacity to see is the eye's fire recognizing the world's fire.

This ontology immediately explains the next clause of the verse. Tasya viśeṣāt śleṣmato bhayam, "its particular danger is from śleṣman." Śleṣman is another name for kapha, the doṣa composed of the water and earth elements. Kapha's qualities (heavy, cold, wet, slow, dense, sticky) are the direct functional opposite of tejas's qualities (light, hot, dry, fast, clear, radiant). Any accumulation of kapha in the eye acts as a blanket over its fire, obscuring function and risking disease. The morning accumulation of kapha, produced during the kapha-dominant hours of late sleep and concentrated in the upper body generally and the head specifically, is precisely the accumulation that the morning añjana disperses. (Classical timing: kapha dominates from 6 to 10 a.m., pitta 10 a.m. to 2 p.m., vāta 2 to 6 p.m., with the nocturnal cycle repeating.)

The logic is the logic of the entire dinacaryā: each morning practice removes the overnight accumulation of whichever doṣa gathers most heavily at that site. The twig clears kapha from the mouth. The añjana clears kapha from the eyes. The nasya (coming in verse 6) clears kapha from the sinuses and brain. The gargle clears kapha from the throat. Each sense-gate of the head has a tailored practice because each sense-gate is subject to the same overnight kapha load, and each requires a specific instrument to clear it.

Nityam: daily, not occasionally

The single word nityam ("daily, constantly") carries clinical weight. Āyurvedic pharmacology recognizes two broad classes of topical applications: those that are used daily as preventive maintenance (nitya-yoga) and those applied only in disease (naimittika-yoga, "for a specific cause"). Sauvīrāñjana is classified as nitya. It is preventive, not therapeutic. It is not waiting for symptoms; it is maintaining the tejas-kapha balance of the eye as an ongoing condition of health.

The weekly rasāñjana application (verse 6) is different. That is a stronger, more irritant preparation, made from the bitter decoction of dāruharidrā (Berberis aristata, the Indian barberry), used to actively drain accumulated kapha through induced lacrimation. Sauvīrāñjana is the daily maintenance; rasāñjana is the weekly clearing. The pairing is classical: a gentle daily practice plus a stronger periodic cleansing, each calibrated to what the tissue can tolerate at the chosen interval.

A word on the cosmetic dimension

The blackening of the eye's rim with añjana is, in the classical tradition, simultaneously a medical and an aesthetic practice. The two are not separated as they are in modern cosmetic culture. A properly applied añjana protects the eye from glare (the same function dark makeup around the eye performs in modern sport, e.g., the eye-black of baseball players), reduces photosensitivity, highlights the contrast between the pupil and the surrounding tissue, and (as a byproduct of its pharmacology) produces the clarity and brightness of the sclera that the tradition reads as a sign of good ocular health.

The ancient physicians noticed that women and men who applied añjana daily had eyes that remained clear and bright into advanced age, while those who did not often developed the opacities and infections that were the most common causes of blindness in the classical world. Whether the mechanism was antimicrobial, anti-inflammatory, or simply the protective effect of daily attention to the eye's cleanliness, the empirical outcome was reliable enough to be codified in the dinacaryā.

Verse 6 will extend the teaching with the weekly rasāñjana and will mark the transition to the other four morning practices of the head region: nasal drops, mouth gargle, herbal smoke, and betel chewing.

The practice of applying a mineral-based salve to the eyes is one of the most geographically and historically widespread traditions in the history of personal care. Archaeological and textual evidence establishes its presence across virtually every major ancient civilization.

In Egypt, kohl-application is documented from the Predynastic period (c. 3100 BCE) onward. The Ebers Papyrus (c. 1550 BCE) specifies formulations for both cosmetic and therapeutic use, and tomb goods from the 18th Dynasty onward routinely include kohl jars and applicators. Egyptian analysis of kohl residues has identified galena (lead sulphide), stibnite (antimony sulphide), malachite (copper carbonate), and charcoal as the principal pigments, with variable plant and fat binders. A 2010 study published in Analytical Chemistry by Tapsoba, Walter, and colleagues (full citation: Tapsoba I., Arbault S., Walter P., Amatore C., "Finding out Egyptian Gods' Secret Using Analytical Chemistry," Analytical Chemistry 82:2, 457–460, 2010) found that the lead-based compounds in Egyptian kohl stimulated nitric oxide production in skin cells, activating an immune response that likely conferred antimicrobial protection against the bacterial eye infections endemic to the Nile delta. The Egyptian practice appears to have been pragmatic as well as aesthetic.

In Mesopotamia, kohl preparation is described in Akkadian medical tablets from Nineveh, with recipes preserved in cuneiform that specify both the mineral ingredients and the method of grinding and application. The trade in kohl minerals was extensive: stibnite from the Iranian plateau, malachite from the Sinai, galena from Anatolia, all reaching Sumerian and Babylonian markets along the same routes that carried lapis lazuli and tin.

The Islamic tradition inherited and formalized the practice through the Prophetic recommendation of ithmid (antimony kohl), distinct from the lead-based kohls of common Egyptian use. Multiple hadith record the Prophet Muhammad as using ithmid before sleep and recommending it for its clarifying and strengthening effect on the eye. The Arabic al-kuḥl entered Medieval Latin as alcohol, originally meaning the fine antimony powder itself; the word later generalized to any finely pulverized or distilled substance, and only in the 18th century narrowed to ethanol. Ibn Sīnā's Canon of Medicine devotes extensive attention to ocular pharmacology, including detailed preparation instructions for antimony-based kuḥl for therapeutic use in conjunctivitis, corneal inflammation, and age-related visual decline.

The Persian sormeh tradition preserves a close cognate of the Āyurvedic practice, with antimony-based preparations still available in traditional bazaars in Iran and across the Central Asian steppes. Persian physicians of the Safavid period produced detailed pharmacopoeias on eye-care, with sections on the daily use of sormeh that read almost as direct translations of Vāgbhaṭa's verse.

In Traditional Chinese Medicine, the approach to eye care is different in form but similar in principle. Chinese ophthalmology classically pairs acupuncture at specific points around the eye with internally taken herbal formulas to clear "damp-heat" or "wind-heat" from the liver channel (the liver is understood to open into the eyes in TCM anatomy). Topical applications were less prominent, but the Yinhai Jingwei (銀海精微, a Chinese ophthalmology text traditionally attributed to Sun Simiao, preserved in the form we have from the Yuan or early Ming period) does describe mineral-based eye preparations with compositions analogous to Āyurvedic añjanas. The underlying recognition, that the eye is a tissue requiring specific preventive care, is constant across traditions, even when the specific intervention differs.

Greek and Roman medicine included eye-salves among their standard pharmacological preparations. Pliny the Elder's Natural History describes multiple formulations using stibnite, zinc oxide, and various plant extracts. The archaeological record in Roman Britain and Gaul has yielded small cylindrical stone "oculist stamps" used to mark the dried cakes of eye-salve produced by Roman oculists, evidence of an organized trade in therapeutic ophthalmological preparations across the empire.

The universal element across all these traditions is the understanding that the eye, being constantly exposed to dust, sunlight, pathogens, and the accumulated secretions of sleep, requires active daily care rather than passive cleanliness. The specific mineral used varies with geography; the specific technique varies with culture; the underlying recognition, that eye-care is part of the daily regimen of health, not merely of beauty, is constant. Vāgbhaṭa's single śloka encodes the universal finding and adds the doctrinal frame that makes it precise: the eye is tejomaya, threatened by śleṣman, and protected by the daily application of a clearing mineral.

The universal principle of this verse can be stated in one line: a highly refined sense organ requires highly specific maintenance. The eye is not a general tissue. It is a structure evolved to perform one function (the perception of light) with extraordinary precision, and like every precision instrument it needs attention tailored to what it does.

The classical tradition recognizes this by assigning each sense organ its own element, its own characteristic vulnerability, and its own maintenance practice. The ear does not receive añjana. The skin does not receive gargle. The nose does not receive twigs. Each sense has its own instrument of care. This is not arbitrary. It reflects the recognition that the practices must fit the specific physiology of the specific tissue, and a generic "wellness routine" that applies the same action to every part of the body does not replicate the precision the classical texts achieved.

The second universal is encoded in the tejas-śleṣman framing: every capacity has a corresponding vulnerability, and the vulnerability is the direct opposite of the capacity. The eye's capacity is to see, which is the capacity of fire. Its vulnerability is to obscuration, which is the action of water-and-earth on fire. A tissue that is extraordinary at one thing is especially fragile in the opposite direction. This pattern extends beyond the eye:

• The digestive system's capacity is to transform; its vulnerability is to stagnation.
• The nervous system's capacity is to respond quickly; its vulnerability is to depletion and dysregulation.
• The immune system's capacity is to distinguish self from non-self; its vulnerability is to confusion of that distinction (autoimmune conditions).
• The reproductive system's capacity is to generate new life; its vulnerability is to the blockage or derangement of that generation.

In each case, the practices that preserve the capacity are practices that counteract the specific vulnerability. Preserving digestion requires keeping things moving (warm foods, fiber, adequate fat to prevent dryness-stagnation). Preserving the nervous system requires practices that replenish what it expends (sleep, silence, stillness). Preserving the immune system requires practices that maintain the clarity of self-recognition (nutrition, sleep, reduced inflammatory load). Preserving the reproductive system requires practices that keep the relevant channels open and nourished.

The third universal is the nityam principle: preventive practice, done reliably at low intensity, is more effective than therapeutic intervention at high intensity after the system has failed. This is not unique to eye-care. It is the general logic of maintenance over repair. The daily application of añjana is less dramatic than the removal of a cataract, and it is also less expensive, less risky, and more effective at preserving the tissue that repair surgery can at best restore. A tradition that has built in the daily maintenance does not produce the diseases that require the repair.

The modern body receives the reverse lesson from contemporary medical culture. Prevention is framed as a private responsibility pursued in whatever time remains after work and family obligations. Intervention is the site of professional expertise, insurance coverage, and social recognition. The incentives point the practitioner toward the emergency room and away from the morning routine. Vāgbhaṭa's dinacaryā encodes a different incentive structure: the morning routine is the site of serious expertise, and the emergency is the failure case that a well-executed routine is designed to prevent.

The fourth universal is subtle but important: the cosmetic and the medical are not separate domains. The añjana protects the eye and it outlines the eye. The tooth-twig cleans the teeth and it freshens the breath. The oil massage nourishes the tissue and it produces the glow of healthy skin. The classical tradition does not separate what a practice does for the user's health from what it does for the user's appearance, because the distinction is artificial. A healthy body looks like a healthy body. A body that has been cared for shows the care. Practices that produce only the appearance without the underlying health are cosmetically shallow and ultimately fail; practices that produce only the health without the appearance are incomplete, because the appearance is the visible read on the state of the tissue. Vāgbhaṭa's añjana is both.

The añjana practice is still alive. In 2026 a reader can purchase kohl, kājal, surmā, or sormeh in any neighborhood with a significant South Asian, Middle Eastern, or North African population, and can apply it to the eyes each morning using the technique Vāgbhaṭa describes. The practice is not extinct. What has changed is the safety landscape around the product, and the modern reader needs accurate information about what to look for and what to avoid.

1. The lead problem

The classical Āyurvedic sauvīrāñjana is stibnite (antimony trisulphide, Sb₂S₃). The classical Egyptian and Levantine kohl is often a mixture of stibnite and galena (lead sulphide, PbS). Galena is chemically similar in appearance to stibnite and has been used interchangeably for millennia in visible preparation. The distinction was not medically significant in the classical period, but it is medically significant now.

Lead is a cumulative neurotoxin. Chronic application of lead-based kohl, particularly to children's eyes, has been documented to elevate blood lead levels and contribute to the lead-related cognitive deficits observed in populations with heavy cosmetic lead exposure. The U.S. FDA has explicitly warned against the import and use of kohl products containing lead (Import Alert 53-15, "Detention Without Physical Examination of Eye Area Cosmetics Containing Kohl, Kajal, or Surma," and the FDA consumer page on lead-contaminated kohl), and multiple seizures of lead-heavy kohl at U.S. ports of entry have been reported. The UK, EU, and Australia maintain similar restrictions.

A modern reader wanting to adopt the classical practice has two workable paths.

1. Source genuine antimony-based kohl from a trusted supplier. Look for products explicitly labeled "100% stibnite," "antimony kohl," or ithmid (the Prophetic name for pure antimony preparations). Saudi Arabian and Iranian suppliers often stock pure ithmid. Read the ingredient list; reject any product that lists galena or lead, or that is unwilling to specify its composition. A product that has been independently tested for heavy metal content (some reputable Middle Eastern suppliers publish lab analyses) is safer still.
2. Use modern herbal alternatives. Several Indian and Middle Eastern brands now produce kājal formulated from plant-derived carbon (burned almond or ghee-charred cotton) with castor oil, camphor, and saffron, explicitly without mineral pigments. These lack the antimicrobial activity of the classical antimony preparation but are safe, gentle, and preserve the cosmetic and light-protective functions. Himalaya and Biotique produce plant-carbon kājals without mineral pigments. Product formulas change over time, so check the ingredient list on each new purchase and avoid any product that lists galena or lead.

2. Application technique

The classical method applies a small amount of the prepared añjana to the inner rim of the lower eyelid (the vartmā), not to the eyeball or the outer lash line. A small rod (traditionally gold, silver, or a smooth piece of wood; in modern practice, a clean wooden or plastic applicator) is dipped into the preparation and drawn gently along the inside of the lower lid margin from inner to outer corner. The eye is closed briefly; the kohl distributes across the tear film as the eye reopens. The entire application takes about fifteen seconds per eye.

Key technique points:

• The applicator must be clean. Shared applicators are a known source of bacterial conjunctivitis. Use a dedicated one, and clean it weekly with warm water and mild soap.
• The preparation must be stored closed to prevent contamination. Many traditional containers are specifically designed to seal the kohl between uses.
• Do not apply if the eye is currently inflamed, infected, or injured. This matches the contraindication logic of verse 4 for the mouth: acute disease states require withholding the preventive practice and seeking tissue quiet before resuming.
• Contact lens wearers should insert lenses before applying any eye cosmetic, and avoid waterline application altogether. Mineral or carbon particulate migrating between lens and cornea can scratch the lens or cause abrasion. If you wear contacts, stick to a line along the outer lash margin rather than the inner rim.

3. Daily practice as the point

The specific instrument matters less than the consistency of application. A reader using plant-carbon kājal daily is closer to Vāgbhaṭa's teaching than a reader using authentic ithmid once a month. The verse's nityam is the operative word: the practice is preventive, and prevention requires reliability over time. A bottle of kājal on the bathroom counter, used for thirty seconds each morning after washing the face, is the practice's modern form.

4. What the daily practice is good for

The documented benefits of consistent morning añjana application, across both traditional accounts and the modern evidence base, include:

• Reduced ocular surface dryness, particularly useful for screen-heavy work patterns.
• Reduced bacterial load on the eyelid margin (especially with antimony preparations), with some published evidence against Staphylococcus species commonly implicated in blepharitis.
• Reduced glare sensitivity, with the pigmented lid margin functioning similarly to athletic eye-black.
• Increased clarity of the sclera (the white of the eye) with continued use, noted by practitioners across cultures.
• The subjective sense of the eyes feeling "clean" and "ready" for the day, which is what the verse's hitam ("beneficial") literally points at.

The practice will not cure existing pathology. A reader with chronic blepharitis, refractory dry eye, or any ocular disease should work with an ophthalmologist; añjana is preventive care, not treatment. For the healthy reader, it is one of the simplest, cheapest, and most consistently documented morning practices in the classical tradition.

5. What verse 6 adds

The next verse introduces the weekly rasāñjana, a stronger Berberis-based preparation used to actively drain kapha through induced lacrimation. That practice is more intense and done at longer intervals, and it transitions the chapter into the other four morning practices for the head: nāvana (nasal drops), gaṇḍūṣa (mouth gargle), dhūma (herbal smoke), and tāmbūla (betel). Together verses 5 and 6 complete the Añjana sub-section and set up the rest of the morning regimen.
