Know That by long prostration, by estion and by service; the wise who have realised the Truth will instruct thee in (that) knowledge.

Learn it by bowing down, by asking questions and by serving. The wise, who have seen the truth, will teach you knowledge.

Krishna explains how such knowledge is gained. It comes through praṇipāta, humble approach and bowing; paripraśna, sincere and searching questions; and sevā, service to the teacher. Those who have seen the truth, tattvadarśins, will then share it. The verse describes the ideal relationship between student and teacher in Indian tradition: humility without blind acceptance, since questioning is encouraged, and devotion shown through service. It also implies that this knowledge is passed from person to person, not merely read.
