These days, many practitioners of Yoga are aware of Bhakti. Those who practice Bhakti are aware that the greatest form of Yoga is devotion to Krishna, as clearly expressed in the Bhagavad Gita, Chapter 6, Verse 47. But most Yoga and Bhakti practitioners are unaware of the hidden teachings of Bhakti in The Yoga Sūtra of Patañjali. In this talk, Garuda Das, who is preparing a translation of The Yoga Sutra to be published by Yale University Press, will explore some surprising discoveries of how Bhakti is most deeply embedded within the Patañjali's teachings.
