16. Accumulate the yellow color concentrated in the spleen, pancreas and stomach at the "gathering point" which is located just below the navel in the center of the body.
In your mind's eye, see that this sphere is filled with a yellow glow both as you inhale and as you exhale. Hold this mental image for a minute or so.
17. As you exhale, imagine how the yellow color from the “gathering point” is directed into the mouth, then out, spreading in all directions and surrounding your body with a yellow aura. At the same time, imagine how your thumbs, eyelids, armpit hair, and arm hair also give off a yellow glow, combining with the energy flowing from the tip of your tongue.
Spread the yellow light over the surface of the arms, legs, body, back, around the head, between the fingers and in all places where your inner gaze penetrates until the entire body is enveloped in the aura. If you work out in clothes, the glow will penetrate through them.
18. When finishing the exercise, accumulate energy in the navel area.
