Bhagavad Gita Chapter 6, Verse 17

युक्ताहारविहारस्य युक्तचेष्टस्य कर्मसु | युक्तस्वप्नावबोधस्य योगो भवति दुःखहा ||

yuktāhāra-vihārasya yukta-ceṣṭasya karmasu yukta-svapnāvabodhasya yogo bhavati duḥkhahā

But those who are temperate in eating and recreation, balanced in work, and regulated in sleep, can mitigate all sorrows by practicing yoga.

Krishna describes the balanced lifestyle that supports yoga practice. 'Yuktāhāra-vihārasya'—for one who is moderate (yukta) in eating (āhāra) and recreation (vihārasya). This means: balanced eating—not too much, not too little. Balanced recreation—not excessive, not absent. 'Yukta-ceṣṭasya karmasu'—for one who is moderate (yukta) in exertion (ceṣṭasya) in actions (karmasu). This means: balanced work—not overworking, not underworking. 'Yukta-svapnāvabodhasya'—for one who is moderate (yukta) in sleep (svapna) and wakefulness (avabodhasya). This means: balanced sleep—not too much, not too little. 'Yogo bhavati duḥkhahā'—yoga (yogaḥ) becomes (bhavati) the destroyer of sorrow (duḥkhahā). This means: when you live a balanced lifestyle—moderate eating, recreation, work, sleep—yoga practice becomes effective and destroys all suffering. This is the positive counterpart to verse 6.16—instead of extremes preventing yoga, moderation enables it.
