PURPORT

Acaryavan puruso veda: one who is guided by the bona fide spiritual master knows everything as stated in the Vedas, which set forth the standard of infallible knowledge. As recommended in Bhagavad-gita, acaryopasanam: one must approach the acarya for real knowledge. Tad-vijnanartham sa gurum evabhigacchet: one must approach the acarya, for then one will receive perfect knowledge. When guided by the spiritual master, one attains the ultimate goal of life.
