Yoga is the cessation of the turnings of the mind.

Otherwise, the seer identifies with the thoughts in their mind.

Then the Seer abides in Itself, resting in its own True Nature.

Yoga is the cessation of the turnings of the mind.

Yoga Sutra | Samadhi Pada

Now, the teachings of yoga.

Ashtanga Vinyasa Yoga

I love the Chanting of the Sutras in these videos. These are from 1938 at Krishnamacharya's Yoga School in Mysore India. Most of the video is of Iyengar who is 20 at the time. Krishnamarchaya is in there on a few occasions. He was 5o at the time.

Ashtanga Invocation

This mantra is typically done prior to an Ashtanga yoga practice or class. It is in recognition of the multitude of teachers that have come before us and acknowledging Patanjali in particular for his composing the Yoga Sutra.

vande gurunam charanaravinde
sandarsita svatmasukhava bodhe

Translation:
I bow to the lotus feet of the guru(s)
who awaken insight into the happiness of pure Being,
who is the final refuge, like the jungle physician,
who eliminates the delusion caused by the poisonous
herb of samsara [conditioned existence].

I prostrate before the sage Patanjali
who has thousands of radiant, white heads
[in his form as the divine serpent, Ananta]
and who has, as far as his arms,
assumed the form of a man holding a conch shell [divine sound],
a wheel [discus of light, representing infinite time]
and a sword [discrimination]. om
