[43] The consciousness principle (or life-force) leaves the body through the 'Aperture of Bhrama (Skt. Bhrama-randhra) situated on the crown of the head at the sagittal suture where the two parietal bones articulate, opened by means of the yogic practise of the Pho-wa. The bird flying out of it is the consciousness-principle going out; for it is through this aperture that the life-force quits the body, either permanently at death, or temporarily during the practice of Pho-wa. The process is a part of Kundalini Yoga.
