in the center of the heart, and, when the exhalation goes through the right nostril, he should think the Hum word comes out along with the exalted air and enters into and is identified with the Hum word in the skull. Meantime the yogi should hold the air outside as long as possible. When he cannot hold it any longer, he slowly takes the air in. Then he exhales and visualizes as before. Continuing this practice for a while, the yogi will see the skull shake, jump and move--these are the signs that will appear.

The yogi may now proceed to the actual transformation of soul. First, he should procure a fresh corpse with no signs of decomposing, not being dead from any injuries or disease; or he may procure a clean and fresh corpse of cattle or any livestock. Then he washes the corpse with clean water, decorates it with pleasing ornaments, and places it well on the Mandala in a sitting position. Then, the yogi visualizes the Hum word which symbolizes the mind, both in his own heart and that of the corpse. He then arouses his prana to drive the Hum word out through his right nostril and through the corpse's left nostril into the Hum word at the Heart Center. If the yogi practices this again and again, the corpse will start to breathe and to regain its senses. When these signs take place, the yogi should know his performance is effective and should (temporarily) stop the practice.

When the yogi is ready to carry out the real performance, he should release himself from the Confinement and go out to find a qualified and fresh corpse, bring it back, and place it on the Mandala facing him. Having decorated the corpse, the yogi then visualizes the self-Yidam-body and lays aside the attachment to the vulgar human body. He then reminds himself that all Dharmas in the cosmos are

magic-like and illusory. Now it is time for him to cut off all vulgar, fallacious thought, as well as delusory habitual thinking, and render his body as an offering to the gurus and guards.
