Dhanvantari

Dhanvantari is the celestial deity of Ayurveda and medicine, revered as the physician of the devas and an incarnation of Vishnu. According to the Bhagavata Purana (8.8.28-33), Dhanvantari emerged from the churning of the Milk Ocean (Samudra Manthana) bearing a pot of amrita (nectar of immortality), thus becoming the divine healer. The Mahabharata (Vana Parva 115.12) also recounts this episode, describing him as a handsome youth adorned with jewels. In Vedic literature, Dhanvantari is associated with the Ashvins, the twin gods of medicine, but his prominence grows in the Puranas. Iconographically, Dhanvantari is depicted with four arms: holding a pot of amrita, a conch (shankha), a discus (chakra), and a leech or medicinal herbs, symbolizing his healing powers.

His radiant complexion and serene expression reflect his role as a bestower of health and longevity. The Skanda Purana (Kashi Khanda 66.25-30) narrates that Dhanvantari later incarnated as King Divodāsa of Kashi (Varanasi) to teach Ayurveda to sages. This tradition holds that he compiled the Ayurvedic texts, including the Dhanvantari Samhita, though the extant work is attributed to his disciple. Dhanvantari is worshiped primarily on Dhanteras, the first day of Diwali, when devotees seek his blessings for health and prosperity. Dhanvantari Jayanti, his birth anniversary, is celebrated on the full moon day of the month of Kartik.

Regional traditions in South India, especially in Kerala, revere him as the patron of Ayurvedic practitioners, and temples such as the Dhanvantari Temple in Thottuva and the one in Cherthala are dedicated to him. In Hindu cosmology, Dhanvantari represents the divine aspect of healing and the preservation of life, bridging the material and spiritual realms. His association with amrita underscores the quest for immortality, while his role as a teacher of Ayurveda emphasizes the importance of holistic health. The Dhanvantari Gayatri mantra, 'Om Dhanvantaraye Vidmahe Amritakalaya Dhimahi Tanno Dhanvantari Prachodayat,' is chanted for healing and well-being. Thus, Dhanvantari embodies the convergence of mythology, medicine, and devotion in Hindu tradition.

The name Dhanvantari (Sanskrit: धन्वन्तरि) is traditionally derived from 'dhanvan' (धन्वन्), meaning 'bow' or 'curve', and 'tari' (तरि), meaning 'moving' or 'crossing', thus 'moving in a curve' or 'one who moves like a bow'. This likely alludes to the serpentine motion of the churning rod during the Samudra Manthana.

Another interpretation connects 'dhanvan' to 'sand' or 'desert', but this is less accepted. Regional variants include Dhanvamtari in some South Indian traditions.

The name is also associated with 'Abja' (water-born) in the Brahmanda Purana, as Vishnu declared him born from water. The term 'Sudhapāṇi' (one holding nectar in hand) is a common epithet.

Dowson's 1879 dictionary notes the name's Vedic roots, where offerings were made to a deity named Dhanvantari at twilight.

Dhanvantari first appears in the Rigveda (though not by name) as a divine healer associated with the Ashvins. The earliest explicit mention is in the Ramayana (Bala Kanda) and the Bhagavata Purana (8.8.28-33), which describe his emergence from the churning of the Milk Ocean bearing amrita.

The Mahabharata (Vana Parva 115.12) also recounts this episode, depicting him as a handsome youth. The Brahmanda Purana provides a detailed origin story, where Vishnu grants him a boon to incarnate in the second Dvapara Yuga as King Divodāsa of Kashi.

The Skanda Purana (Kashi Khanda 66.25-30) narrates this incarnation and his role in teaching Ayurveda to sages. Dhanvantari's prominence rises in the Puranic period, shifting from a minor Vedic figure to a major deity of medicine.

The Dhanvantari Samhita, though attributed to him, is a later Ayurvedic text.

Four-armed, holding amrita pot, conch, chakra, and leech. Radiant complexion, often depicted with medicinal herbs.

In Advaita Vedanta, Dhanvantari is seen as a manifestation of Vishnu, representing the cosmic principle of preservation through health. His emergence from the ocean symbolizes the manifestation of divine grace in the material world. In Vishishtadvaita, he is a distinct avatar of Vishnu, embodying his role as sustainer of life.

Dvaita traditions emphasize his status as a deity subordinate to Vishnu, yet worthy of worship for health and longevity. In Tantric and Shakta traditions, Dhanvantari is associated with healing mantras and rituals, often invoked for curing diseases. The Dhanvantari Gayatri mantra is chanted for health.

In Vaishnava theology, he is one of the 24 avatars, as listed in the Bhagavata Purana. Commentators like Sridhara Swami highlight his role in bestowing amrita, symbolizing spiritual immortality. The Skanda Purana links him to Kashi, a sacred city for liberation.

Dhanvantari is widely worshipped on Dhanteras, the first day of Diwali, when devotees buy utensils and seek blessings for health. Dhanvantari Jayanti is celebrated on the full moon of Kartik.

In Kerala, he is the patron of Ayurvedic practitioners, with temples like Dhanvantari Temple in Thottuva and Cherthala. In Bharatanatyam, the Samudra Manthana episode is a popular theme.

Carnatic compositions, such as those by Muthuswami Dikshitar, invoke Dhanvantari. In Tanjore paintings, he is depicted with a pot of amrita.

Folk traditions in South India include processions and offerings of medicinal herbs. Pan-Asian spread is limited, but his iconography appears in some Southeast Asian art, influenced by Hindu cosmology.
