Bhagavad Gita Chapter 14.6
tatra sattvaḿ nirmalatvāt
prakāśakam anāmayam
sukha-sańgena badhnāti
jñāna-sańgena cānagha
Translation
O sinless one, the mode of goodness, being purer than the others, is illuminating, and it frees one from all sinful reactions. Those situated in that mode become conditioned by a sense of happiness and knowledge.
