Bhagavad Gita Verse 8.6

हे कुन्तीपुत्र अर्जुन ! यह मनुष्य अन्तकालमें जिस जिस भी भावको स्मरण करता हुआ शरीरका त्याग करता है, उस उसको ही प्राप्त होता है; क्योंकि वह सदा उसी भावसे भावित रहा है|

O Arjuna, whatever entity (being or object) one thinks about during the time of his death while leaving his body, that is what he shall become in his next life.
