śloka 6
tatra sattvaṃ nirmalatvātprakāśakamanāmayam |
sukhasaṅgena badhnāti jñānasaṅgena cānagha ||14-6||
Translation
O sinless Arjuna! Among these (three), the quality of Sattva, being pure, is illuminating and free from affliction (free from disturbance, change or disease); (it) binds the jiva through attachment to pleasure and attachment to knowledge.
