The yogi should visualize himself as the Father and Mother Yidam. At the Dharma Wheel of the Heart Center in the Central Channel stands a blue Hum word on the Sun Disc.

From this Hum word emanate beams of light shining upon all the cosmos and purifying them; then the beams enter and are absorbed into the bodies of all sentient beings.

[paragraph continues] Thereupon, all the sentient beings melt (and are absorbed) into the Mother Yidam. Then, in the downward absorbing process, the head of the Yidam vanishes, then the neck, the chest, etc., one by one, and are finally absorbed in the Hum word. At the same time, in the upward-absorbing process the toes first vanish into the leg, then the leg into the thigh, thigh into hips, hips into belly, and finally all are absorbed into the Hum word. Thereon, the lower part of the Hum word, the vowel u, vanishes into the Ha, and the Ha vanishes into the half-moon; the half-moon then vanishes into the Thig-le [here to be understood as bindu Ed.] and the Thig-le vanishes upward into the Nada. Since this Visualization of the absorbing process is concentrated upon the Heart Center in the Central Channel, if one can stabilize the Visualization, the pranas of the Ro-ma and Rkyang-ma will all enter, remain, and dissolve in the Heart Center in the Central Channel; the Four Voidnesses will successively arise; the Light of Path will augment. At this time, with blissful mind, one should unwaveringly meditate upon the Visualization.

As mentioned before, this commentary on the Illusory Body and Light Yoga is prepared on the pith-instructions of the Pao School. The instruction of the Light Yoga given above is based on the unique teaching of the Five Steps of Gsun-adus and it was introduced here as a little adornment for the pith-instructions.

In the Heat Yoga practice, if one can raise (unfold) the Innate [Wisdom-Bliss] through the entering of prana into the Central Channel, he will easily be able to raise the Innate Light at the time of Light Yoga practice. At least, he will be able to unfold it through the practice of the absorbing process (without difficulty).
