Bhagavad Gita 7.30

7.30 Those who know Me with the Adhibhuta (pertaining to the elements), Adhidaiva (pertaining to the gods) and the Adhiyajna (pertaining to the sacrifice) know Me even at the time of death, steadfast in mind.

Those in full consciousness of Me, who know Me, the Supreme Lord, to be the governing principle of the material manifestation, of the demigods, and of all methods of sacrifice, can understand and know Me, the Supreme Personality of Godhead, even at the time of death.
