Ayurveda is an ancient medical science. As we use it in various ways in daily life we can’t even think where it is with us. In Puranas, we have heard many spiritual stories about gods and devils, and the evolution of Ayurveda is a kind of spiritual story. There are lots of references that show us how Ayurveda is evolved.
Ayurvedavtran is a divine process of transformation of knowledge of Ayurveda and its principles. Various acharyas acquired complete and true knowledge of Ayurveda from their guru. This was a traditional example of a conference and discussion with their guru and colleagues.
According to Charak Samhita
ब्रह्मणा हि याथाप्रोक्तामायुर्वेदं प्रजापतिः|
जग्राह निखीलेनादाव्श्विनौ तु पुनस्तत:||
आश्विभ्यां भगवाञछक्र: प्रतिपेदे ह केवलम्|
