Prabhupada Letters :: 1971.

"The Vedas gives specific instruction how to swim over this material ocean, but if the rascal does not take the instruction through the bona fide representative, the Spiritual Master, then he becomes drowned."

Prabhupada Letters :: 1970.

"If you follow my instructions there is no doubt that through me, my Spiritual Master will be pleased, and through His mercy, Lord Nityananda। In this way Lord Caitanya and ultimately Radha Krsna will be pleased - and thus your life will be successful."
