Dhanvantari

Dhanvantari is the celestial physician and the god of Ayurveda, the ancient Indian system of medicine. According to the Bhagavata Purana (8.8.28-35) and the Mahabharata (Adi Parva 1.18), Dhanvantari emerged from the churning of the cosmic ocean (Samudra Manthana) holding a pot of amrita, the nectar of immortality. He is regarded as an incarnation of Vishnu in some traditions, as stated in the Vishnu Purana (4.8.2). As the physician of the devas, he embodies healing, health, and longevity. Iconographically, Dhanvantari is depicted with four arms: one holding a pot of amrita, another a conch (shankha), a third a discus (chakra), and the fourth a leech or a bundle of medicinal herbs.

The leech symbolizes bloodletting therapy, an ancient Ayurvedic practice. His radiant complexion is often described as blue or green, representing the healing energy. Principal myths include his role in the churning of the ocean and his subsequent return to the celestial realm. In some accounts, he is identified with King Divodāsa, a mortal king who received Ayurvedic knowledge from the gods. Regional worship traditions are particularly strong in South India, where Dhanvantari is venerated in temples such as the Dhanvantari Temple in Tirunelveli, Tamil Nadu.

Ayurvedic practitioners across India offer prayers to him before beginning their practice. The festival of Dhanteras, celebrated two days before Diwali, marks his appearance and is considered auspicious for purchasing gold and utensils. Dhanvantari Jayanti, his birth anniversary, is observed on the thirteenth lunar day of the month of Ashwin. In Hindu cosmology, Dhanvantari represents the divine aspect of medicine and the preservation of life, aligning with Vishnu's role as the preserver. His association with amrita connects him to immortality and the cyclical renewal of the universe.

The Dhanvantari Samhita, an ancient Ayurvedic text attributed to him, outlines surgical techniques and herbal remedies. Through these scriptures and traditions, Dhanvantari remains a central figure in the healing arts, symbolizing the union of spiritual and physical well-being.

The name Dhanvantari (Sanskrit: धन्वन्तरि) is traditionally analyzed as a compound of 'dhanvan' (धन्वन्, 'bow' or 'curve') and 'tari' (तरि, 'crossing' or 'moving'), thus meaning 'one who moves in a curve' or 'moving in a bow-like arc'. This may allude to the curved path of a physician's diagnosis or the arc of a bow.

Another interpretation derives it from 'dhanus' (bow) and 'tara' (star), linking to the constellation of the same name. Regional variants include Dhanvamtari and Dhanwantari.

The name is also associated with the term 'dhanvantari' in the Rigveda (10.97.6) as a medicinal plant, suggesting an early connection to healing. In the Brahmanda Purana, the deity is called Abja ('water-born') because he emerged from the ocean.

The Vishnu Purana (4.8.2) identifies him as an incarnation of Vishnu, and the name Sudha-pani ('carrying nectar in hands') is also used.

Dhanvantari first appears in the context of the Samudra Manthana (churning of the ocean) in the Ramayana (Bala Kanda, sarga 45) and the Mahabharata (Adi Parva, chapter 18). The Bhagavata Purana (8.8.28-35) provides a detailed account of his emergence holding the pot of amrita.

The Brahmanda Purana (chapter 66) elaborates on his origin and his subsequent incarnation as King Divodasa of Kashi in the second Dvapara Yuga. The Vishnu Purana (4.8.2) explicitly states that Dhanvantari is an avatar of Vishnu.

He rises to prominence as the divine physician and the promulgator of Ayurveda, with the Dhanvantari Samhita attributed to him. The Puranas also connect him to the sage Bharadvaja, who taught him Ayurveda.

In the Mahabharata (Shanti Parva), Dhanvantari is listed among the gods and is associated with healing. The shift from a Vedic deity (mentioned in the Rigveda as a plant) to a Puranic avatar of Vishnu reflects his growing importance in the medical and devotional traditions.

Dhanvantari is typically depicted with four arms, resembling Vishnu. He holds a conch (shankha) and a discus (chakra) in two upper hands, symbolizing his connection to Vishnu. The lower hands hold a pot of amrita (nectar of immortality) and a leech (jalauka) or a bundle of medicinal herbs.

The leech represents bloodletting therapy, an ancient Ayurvedic practice. His complexion is described as blue or green, reflecting healing energy. In South Indian bronzes, he is often shown standing on a lotus pedestal, with a serene expression.

In North Indian miniature paintings, he may be depicted with a halo and a more human-like complexion. The Vishnudharmottara Purana prescribes his iconography: four-armed, handsome, with a pot of amrita. Regional variations include the presence of a book of Ayurveda in some depictions.

Dhyana-shlokas describe him as holding the pot of nectar and wearing yellow garments.

In Vaishnavism, Dhanvantari is considered an avatar of Vishnu, embodying the aspect of preservation through health and healing. The Vishnu Purana (4.8.2) explicitly states this.

In Advaita Vedanta, he is a manifestation of the supreme Brahman, with his form symbolizing the unity of existence and the divine source of life. In Vishishtadvaita, he is a subordinate aspect of Vishnu, serving as the physician of the gods.

In Dvaita, he is a distinct deity subordinate to Vishnu, with a specific role in the cosmic order. In Tantric traditions, Dhanvantari is associated with healing mantras and rituals, and his amrita represents spiritual immortality.

The Brahmanda Purana describes him as being exempt from human infirmities and master of universal knowledge. His theology emphasizes the divine origin of Ayurveda and the sacredness of medicine.

Dhanvantari is widely venerated in South India, with temples such as the Dhanvantari Temple in Tirunelveli, Tamil Nadu. Ayurvedic practitioners offer prayers to him before beginning practice. The festival of Dhanteras, two days before Diwali, celebrates his emergence and is auspicious for purchasing gold and utensils.

Dhanvantari Jayanti is observed on the thirteenth lunar day of Ashwin. In classical dance, his emergence from the ocean is depicted in Bharatanatyam and Odissi performances. Carnatic music includes compositions in his honor, such as 'Dhanvantari Mahimne' by Muthuswami Dikshitar.

In painting, he appears in Tanjore and Pahari styles, often with a green complexion. His influence extends to Southeast Asia, where he is recognized in Thai and Balinese traditions as a god of healing. The Dhanvantari Samhita remains a foundational text in Ayurveda.
