"Regarding your questions are the Spiritual Master and the Grand Spiritual Master consciously aware of the prayers of a sincere devotee who prays in love to Them?—the answer is that no conscious prayers go in vain. They are transmitted positively. But one thing you must know that any prayer you offer to your Spiritual Master and Superior Spiritual Master, all of them are conveyed to Krishna, so no sincere prayers go in vain."
(Srila Prabhupada Letter, April 27, 1970)
