śloka 15
rajasi pralayaṃ gatvā karmasaṅgiṣu jāyate |
tathā pralīnastamasi mūḍhayoniṣu jāyate ||14-15||
Translation
Meeting death while Rajas is predominant, he is born among those attached to action (in the human world); and when death occurs while Tamas is predominant, he is born in a deluded womb.
