Srimad-Bhagavatam: Canto 11 - Chapter 1 - Verse 14

Sanskrit:

महत्यात्मनि य: सूत्रे धारयेन्मयि मानसम् ।प्राकाम्यं पारमेष्ठ्यं मे विन्दतेऽव्यक्तजन्मन: ॥ १४ ॥

ITRANS:

mahaty ātmani yaḥ sūtredhārayen mayi mānasamprākāmyaṁ pārameṣṭhyaṁ mevindate ’vyakta-janmanaḥ

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 prākāmya.

Purport:

Śrīla Vīrarāghava Ācārya explains that the word sūtra, 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 prākāmya. Avyakta-janmanaḥ 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 prākāmya or any other genuine mystic perfection.
