The Yoga of Liberation by Renunciation

Krishna introduces the teaching about the three kinds of happiness. 'Sukhaṁ tv idānīṁ trividhaṁ śṛṇu me bharatarṣabha'—hear (śṛṇu) from Me (me) now (idānīm) about the three kinds (trividham) of happiness (sukham), O best of the Bharatas (bharatarṣabha). 'Abhyāsād ramate yatra duḥkhāntaṁ ca nigacchati'—by practice of which (yatra abhyāsāt) one rejoices (ramate) and reaches (nigacchati) the end of suffering (duḥkhāntam). This sets up the detailed teaching about how happiness is classified according to the three gunas: sattvic, rajasic, and tamasic. Understanding this helps you recognize the quality of your happiness and how it leads to or away from the end of suffering. The teaching will show that sattvic happiness, though initially difficult, leads to the end of suffering, while rajasic and tamasic happiness create more suffering.
