When one does not hear, and smell and taste, and see; when one does not feel any touch; when one's mind is perfectly free from every purpose; when one is not conscious of any thing, when one cherishes no thought, when one becomes like a piece of wood, then is he called by the wise to be in perfect Yoga.
न शृणोति न चाघ्राति न रंस्यति न पश्यति। न च स्पर्श विजानाति न संकल्पयते मनः॥ न चाभिमन्यते किंचिन्न न बुध्यति काष्ठवत्। तदा प्रकृतिमापनं युक्तमाहुर्मनीषिणः॥
