Srila Prabhupada worships Srila Bhaktisiddhanta Sarasvati Thakur (Album of photos)

My Guru Mahārāja, my spiritual master, used to say that you have to select a spiritual master not by seeing but by your ear, but by hearing. And you don’t select a spiritual master who has got a very good hair or beard or some very beautiful feature, ‘Oh, he is a very good, nice looking.’ No. You must hear. Tad viddhi praṇipātena (BG 4.34). Śruti. The whole process is śruti. The Vedas are called śruti. The ear has to aural reception.”
(Srila Prabhupada Lecture, New York, August 12, 1966)
