Verse
नैव किंचित्करोमीति युक्तो मन्येत तत्त्ववित् ।पश्यञ्शृण्वन्स्पृशञ्जिघ्रन् नश्नंगच्छन्स्वपन्श्वसन् ॥
The man who knows the principles of things thinks, his mind in Yoga (with the inactive Impersonal), “I am doing nothing”; when he sees, hears, tastes, smells, eats, moves, sleeps, breathes, speaks, takes, ejects, opens his eyes or closes them, he holds that it is only the senses acting upon the objects of the senses.
Gītā 5·8
