Verse
सर्वद्वाराणि संयम्य मनो हृदि निरुध्य च ।मूध्न्यार्धायात्मनः प्राणम् आस्थितो योगधारणाम् ॥
All the doors of the senses closed, the mind shut in into the heart, the life-force taken up out of its diffused movement into the head, the intelligence concentrated in the utterance of the sacred syllable OM and its conceptive thought in the remembrance of the supreme Godhead, he who goes forth, abandoning the body, he attains to the highest status.
Gītā 8·12
