This song consists of a woman with a really beautiful voice reciting a prayer. SWIM had to know what it was all about.

This is the Sanskrit version that she recites:

Yogena cittasya padena vacam malam sarirasya ca vaidyakena yopakarottam pravaram muninam patanjalim pranajaliranato'smi abahu purusakaram sankha cakrasi dharinamsahasra sirasam svetam pranamami patanjalim.

This is the English interpretation:

Let us bow before the noblest of sages Patanjali, who gave yoga for serenity and sanctity of mind, grammar for clarity and purity of speech and medicine for perfection of health. Let us prostrate before Patanjali, an incarnation of Adisesa, whose upper body has a human form, whose arms hold a conch and a disc, and who is crowned by a thousand-headed cobra.

This is perfect for starting a yoga routine.
