Bhagavad Gita 18.75

व्यासप्रसादाच्छ्रुतवानेतद्गुह्यमहं परम्।योगं योगेश्वरात्कृष्णात्साक्षात्कथयतः स्वयम्॥

vyāsaprasādācchrutavānetadguhyamahaṃ param |yogaṃ yogeśvarātkṛṣṇātsākṣātkathayataḥ svayam ||

Through the grace of Vyasa, I have heard this supreme and most secret Yoga, directly from Krishna, the Lord of Yoga, Himself declaring it.

Through the blessing of the sage Vyasa, I heard this secret and noble science from the lips of its Master, Lord Shri Krishna.

Our plain-language meaning of this verse is waiting for scholar review.
