yaṁ yaṁ vāpi smaran bhāvaṁ
yaṁ yaṁ vāpi smaran bhāvaṁ tyajaty ante kalevaram |
taṁ tam evaiti kaunteya sadā tad-bhāva-bhāvitaḥ ||
(Śrīmad Bhagavad-gītā: 8.6)
“O Kaunteya, whatever object one remembers as one leaves the body at death—exactly that one attains, [on account of] being constantly absorbed in thought of that.”
