व्यासप्रसादाच्छ्रुतवानेतद् गुह्यमहं परम् ।

vyāsaprasādācchrutavānetad guhyamahaṃ param .
yogaṃ yogeśvarātkṛṣṇātsākṣātkathayataḥ svayam .. 75 ..


Through the grace of Vyāsa have I heard this Supreme and most secret Yoga direct from Kṛṣṇa, the Lord of Yoga, Himself declaring it.
Read the commentary
Through the grace of Vyāsa: by obtaining from him the divya-chakshus or divine vision. Yoga: this dialogue; the work is called Yoga because it leads to Yoga. Or, the word may mean Yoga itself. Himself: it is not through mere tradition that I have heard it.
