Bhagavad Gita 14.14
When purity prevails, the soul, upon leaving the body, passes on to the pure regions where those who know the Highest reside.
यदा सत्त्वे प्रवृद्धे तु प्रलयं याति देहभृत्।तदोत्तमविदां लोकानमलान्प्रतिपद्यते॥yadā sattve pravṛddhe tu pralayaṃ yāti dehabhṛt|tadottamavidāṃ lokānamalānpratipadyate||
