Śrīmad-Bhāgavatam · Text 11.15.14
Who is speaking and story frame
महत्यात्मनि य: सूत्रे धारयेन्मयि मानसम् ।
प्राकाम्यं पारमेष्ठ्यं मे विन्दतेऽव्यक्तजन्मन: ॥ १४ ॥
mahaty ātmani yaḥ sūtre
dhārayen mayi mānasam
prākāmyaṁ pārameṣṭhyaṁ me
vindate ’vyakta-janmanaḥ
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.
