Krishna defines yoga and describes how to practice it. 'Taṁ vidyād duḥkha-saṁyoga-viyogaṁ yoga-saṁjñitam'—know (vidyāt) that (tam) state called (saṁjñitam) yoga (yoga), which is the disconnection (viyogam) from union (saṁyoga) with pain (duḥkha). This means: yoga is the state where you're disconnected from pain—you're no longer united with suffering, no longer identified with it, no longer bound by it. You're free from the connection to pain. 'Sa niścayena yoktavyaḥ'—that (saḥ) should be practiced (yoktavyaḥ) with determination (niścayena). This means: practice yoga with resolve, with commitment, with firmness—don't be half-hearted. 'Yogo 'nirviṇṇa-cetasā'—yoga (yogaḥ) with undespairing (anirviṇṇa) mind (cetasā). This means: practice with a mind that doesn't despair, that doesn't give up, that doesn't get discouraged. Even when progress is slow, even when challenges arise, don't despair—keep practicing. This is the definition of yoga—disconnection from pain—and the attitude for practice—determination and undespairing mind.
How this ancient wisdom applies to your daily life

Yoga is the disconnection from union with pain—you're no longer united with suffering, no longer identified with it, no longer bound by it. You're free from the connection to pain. This is what yoga means—freedom from suffering. And it should be practiced with determination—firm resolve, commitment, not half-hearted. And with an undespairing mind—don't give up, don't get discouraged, even when progress is slow, even when challenges arise. Keep practicing. This is the definition of yoga—disconnection from pain—and the attitude for practice—determination and undespairing mind. Practice with resolve, practice without despair, and you'll achieve the disconnection from pain.

Are you disconnected from union with pain, or are you still identified with suffering? Are you practicing with determination and an undespairing mind, or are you giving up when progress is slow?
