Invocation to Patañjali
The chant used to open Aṣṭāṅga Vinyāsa classes. Aṣṭāṅga Vinyāsa is the style of yoga popularized by Śrī K. Pattabhi Jois. The first part of the chant is from Yoga Tārāvali of Śaṅkarācārya. It is not Vedic; it is Classical (from a later period), and it does not have a set svara. Therefore, it can be chanted with many different melodies.
I bow before the noblest of sages, Patañjali, who brought serenity of mind by his work on Yoga, clarity of speech by his work on grammar, and purity of body by his work on medicine.
