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-gayatri mantra awarded at the moment of brahmana 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.
Thus end the purports of the humble servants of His Divine Grace A.C. Bhaktivedanta Swami Prabhupada to the Eleventh Canto, Sixteenth Chapter, of the Srimad-Bhagavatam, entitled “The Lord’s Opulence.”
