SB 11.15.14
mahaty atmani yah sutre
dharayen mayi manasam
prakamyam paramesthyam me
vindate ’vyakta-janmanah
Translation:
One who concentrates all mental activities in Me as the Supersoul of that phase of the mahat-tattva which manifests the chain of fruitive activities obtains from Me, whose appearance is beyond material perception, the most excellent mystic perfection called prakamya.
Purport:
Srila Viraraghava Acarya explains that the word sutra, or “thread,” is used to indicate that the mahat-tattva sustains one’s fruitive activities just as a thread sustains a row of jewels. Thus by fixed meditation on the Supreme Personality of Godhead, who is the soul of the mahat-tattva, one can achieve the most excellent perfection called prakamya. Avyakta-janmanah indicates that the Supreme Personality of Godhead appears from the avyakta, or the spiritual sky, or that His birth is avyakta, beyond the perception of material senses. Unless one accepts the transcendental form of the Supreme Personality of Godhead, there is no possibility of obtaining prakamya or any other genuine mystic perfection.
