Bhagwad Gita
Chapter 14, Verse 6
तत्र सत्त्वं निर्मलत्वात्प्रकाशकमनामयम्।सुखसङ्गेन बध्नाति ज्ञानसङ्गेन चानघ।।14.6।।
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 develop knowledge, but they become conditioned by the concept of happiness.
