At the beginning of Iyengar Yoga classes we chant an invocation to sage Patanjali – the father of yoga.
According to Indian mythology, Patanjali was the incarnation of lord Adisesa. Legend says he fell into the praying hands of Ganukia who had no children. One day she was praying to the Sun God while a little snake in the water in the palms of her hands turned into a human shape. She raised him as her child and named him Patanjali; pata = fall, anjali = the folding of the hands during prayer. https://www.liveyoga.nl/yoga-library/about-yoga/invocation-to-sage-patanjali/
