“One should not only hear submissively from the spiritual master; but one must also get a clear understanding from him, in submission and service and inquiries. A bona fide spiritual master is by nature very kind toward the disciple. Therefore when the student is submissive and is always ready to render service, the reciprocation of knowledge and inquiries becomes perfect.” (Shrila Prabhupada, Bhagavad-gita, 4.34 Purport)
