BG 8.14-16
He who constantly thinketh upon Me, not thinking ever of another, of him I am easily reached, O Pârtha, of this ever-harmonised Yogî. Having come to Me, these Mahâtmâs come not again to birth, the place of pain, non-eternal; they have gone to the highest bliss. The worlds, beginning with the world of Brahmâ, they come and go, O Arjuna; but he who cometh unto Me, O Kaunteya, he knoweth birth no more.
