Srimad-Bhagavatam: Canto 11 - Chapter 1 - Verse 15
Sanskrit:
इन्द्रियाणि मनो बुद्धि: सह वैकारिकैर्नृप ।प्रविशन्ति ह्यहङ्कारं स्वगुणैरहमात्मनि ॥ १५ ॥
ITRANS:
indriyāṇi mano buddhiḥsaha vaikārikair nṛpapraviśanti hy ahaṅkāraṁsva-guṇair aham ātmani
Translation:
My dear King, the material senses and intelligence merge into false ego in the mode of passion, from which they arose; and the mind, along with the demigods, merges into false ego in the mode of goodness. Then the total false ego, along with all of its qualities, merges into the mahat-tattva.
