ŚB 11.16.44
Canto 11, Chapter 16, Text 44
मद्भक्तियुक्तया बुद्ध्या तत: परिसमाप्यते ॥ ४४ ॥
niyacchen mat-parāyaṇaḥ
mad-bhakti-yuktayā buddhyā
tataḥ parisamāpyate
Word by word
tasmāt — therefore; vacaḥ — words; manaḥ — the mind; prāṇān — the life airs; niyacchet — one should control; mat-parāyaṇaḥ — who is devoted to Me; mat — unto Me; bhakti — with devotion; yuktayā — endowed; buddhyā — by such intelligence; tataḥ — thus; parisamāpyate — one fulfills the mission of life.
Translation
Being surrendered to Me, one should control the speech, mind and life air, and then through loving devotional intelligence one will completely fulfill the mission of life.
Purport
One can develop loving devotional intelligence by perfectly chanting the Brahma-gāyatrī mantra awarded at the moment of brāhmaṇa initiation. By clear intelligence, one becomes naturally and spontaneously disinterested in the rewards offered by mental speculation and fruitive activities and takes full shelter of the Supreme Personality of Godhead.
