BG Chap 13 - By hearing one can advance
If one cannot practice any of the methods mentioned to worship the Paramatma, one can still advance by hearing from the right authorities. Those who have faith in the Vedas, though not knowing these methods, begin to worship the Lord upon hearing about Him and the methods from others. They also surpass death. Hearing with faith from authorities has great potency. Being purified by the association of authorities from whom they hear, such people after understanding and practicing the methods surpass death. All men should take advantage of hearing from realized souls and gradually become able to understand everything. The worship of the Supreme Lord will then undoubtedly take place. Lord Caitanya has said that in this age no one needs to change his position, but one should give up the endeavor to understand the Absolute Truth by speculative reasoning.
