Sañjaya explains how he, sitting miles away in a palace, was able to hear a battlefield conversation. He credits it entirely to the mercy and grace of his spiritual master, Vyāsadeva (vyāsa-prasādāc). Through this mystic vision, he heard this supreme, confidential knowledge (etad guhyam ahaṁ param) regarding yoga directly (sākṣāt) from the ultimate master of all mysticism, Krishna Himself (yogeśvarāt kṛṣṇāt), as He was personally speaking it (kathayataḥ svayam).
