Bhagavad Gita 6.17

युक्ताहारविहारस्य युक्तचेष्टस्य कर्मसु। युक्तस्वप्नावबोधस्य योगो भवति दुःखहा

yuktāhāra-vihārasya yukta-cheṣhṭasya karmasu yukta-svapnāvabodhasya yogo bhavati duḥkha-hā

Yoga becomes the destroyer of pain for him who is moderate in eating and recreation (such as walking, etc.), who exercises moderation in action, and who is moderate in sleep and wakefulness.

दुःखोंका नाश करनेवाला योग तो यथायोग्य आहार और विहार करनेवालेका, कर्मोंमें यथायोग्य चेष्टा करनेवालेका तथा यथायोग्य सोने और जागनेवालेका ही सिद्ध होता है।
