Remembrance and Prayers also can give us the desired result if they are properly done under expert guidance.
In the Brahma-samhita it is said that the Lord is never to be found by becoming a great scholar of the Vedic literatures, but He is very easily approachable through His pure devotees. In Vrindavana all the pure devotees, thus, pray for the mercy of Srimati Radharani, the pleasure potency of Lord Krishna.
Lord Sri Krishna is the property of His pure unconditional devotees and only the devotees can deliver Krishna to another devotee. Krishna is never obtained directly.
As a highly potent drug injected intravenously acts at once on the whole body, the transcendental topics of the Lord injected through the ear of the pure devotee of the Lord can act very efficiently. Aural realization of the transcendental messages implies total realization, just as fructification of one part of a tree implies fructification of all other parts. This realization for a moment in the association of pure devotees like Sukadeva Gosvami prepares one's complete life for eternity.
