mahati -- in the mahat-tattva; atmani -- in the Supersoul; yah -- one who; sutre -- characterized by the chain of fruitive activities; dharayet -- should concentrate; mayi -- in Me; manasam -- the mental activities; prakamyam -- the mystic perfection called prakamya; parameshthyam -- most excellent; me -- from Me; vindate -- obtains or enjoys; avyakta-janmanah -- from Him whose appearance in this world cannot be materially perceived.
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.
