Bhagavad Gita 2.64 — Free from like and dislike
रागद्वेषविमुक्तैस्तु विषयानिन्द्रियैश्चरन् । (or वियुक्तैस्तु) आत्मवश्यैर्विधेयात्मा प्रसादमधिगच्छति ॥
rāgadveṣavimuktaistu viṣayānindriyaiścaran | orviyuktaistu ātmavaśyairvidheyātmā prasādamadhigacchati ||
Meaning
But a self-controlled person who moves among sense objects with senses free from liking and disliking attains inner peace and clarity.
