Bhagavad Gita Verse 5.8

तत्त्वको जाननेवाला सांख्ययोगी तो देखता हुआ, सुनता हुआ, स्पर्श करता हुआ, सूँघता हुआ, भोजन करता हुआ, गमन करता हुआ, सोता हुआ, श्वास लेता हुआ, बोलता हुआ, त्यागता हुआ, ग्रहण करता हुआ तथा आँखोंको खोलता और मूँदता हुआ भी, सब इन्द्रियाँ अपने-अपने अर्थोंमें बरत रही हैं – इस प्रकार समझकर निःसन्देह ऐसा माने कि मैं कुछ भी नहीं करता हूँ|

He who comes to the realization that, although he is physically performing actions such as seeing, hearing, touching, smelling, eating, walking, sleeping, breathing, speaking, receiving, sacrificing, opening and closing eyes, and so on, that he is actually doing nothing, is a Yogi. O Arjuna, the truly wise Yogi knows that in reality, only the senses are acting among their sense objects.
