Bhagavad Gita Chapter 18.36
sukhaḿ tv idānīḿ tri-vidhaḿ
śṛṇu me bharatarṣabha
abhyāsād ramate yatra
duḥkhāntaḿ ca nigacchati
Translation
O best of the Bharatas, now please hear from Me about the three kinds of happiness by which the conditioned soul enjoys, and by which he sometimes comes to the end of all distress.
