ఆయుర్వేద!

The knowledge of Áyurveda was handed down from Brahmá to Daksha Prajápati, onto the
Ashwin twins (the divine doctors), then passed to Indra. Sage Bharadvája volunteered to go to
heaven to receive this wisdom from Indra, and so became the first human to receive the
knowledge of Áyurveda. He passed it to Átreya, then onto Punarnavasu and finally Agnivesha.
