BG Chap 14 - Destination of persons in different modes
When a person dies with dominance of sattva, he attains the places of heavenly enjoyment of the worshippers of Hiraṇyagarbha (a form of Brahmā) and others. When one dies in the mode of passion, he takes birth among those engaged in fruitive activities or kāmya-karmas. Kāmya karmas are scripturally ordained acts which are optional, performed for fulfilling personal desires, such as begetting children or gaining wealth. When one dies in the mode of ignorance, he is born in the wombs of lower species like the animals.
