Bhagavad Gita · Chapter 6: The Path of Meditation

Bhagavad Gita 6.17

yuktāhāravihārasya yuktaceṣṭasya karmasu | yuktasvapnāvabodhasya yogo bhavati duḥkhahā ||

For one who is moderate in eating and recreation, moderate in effort at work, and moderate in sleeping and waking, yoga becomes the destroyer of sorrow.

Modern context

The positive form follows: moderate in food and recreation, moderate in effort at work, moderate in sleep and waking. The word yukta, 'balanced' or 'fitting', is the same root as yoga. Balance is itself a form of yoga. Notice that recreation is included. Rest and play are part of a balanced life and are not treated as weaknesses. So is effort: too little work leaves a person restless, and too much burns them out.
