8.13  Om, इति thus, एकाक्षरम् onesyllabled, ब्रह्म Brahman, व्याहरन् uttering, माम् Me, अनुस्मरन् remembering, यः who, प्रयाति departs, त्यजन् leaving, देहम् the body, सः he, याति attains, परमाम् supreme, गतिम् goal.Commentary: Having controlled the thoughts the Yogi ascends by the Sushumna, the Nadi (subtle psychic nervechannel) which passes upwards from the heart. He fixes his whole Prana or lifreath in the crown of the head in the Brahmarandhra or the hole of Brahman. He utters the sacred monosyllable Om, meditates on Me and leaves the body.
