Kundalini Abdomen Burst
The agnisara abdomen pollution removal process is long and intricate but it is listed as abdomen flexes in some books which describe the muscular activity which tones the intestines, colon and some other functions and glands in the trunk of the physical body.
Kundalini yoga is for insight into the subtle body. The yogi should infuse fresh air and fresh subtle energy into the physical and subtle bodies simultaneously. When there is sufficient energy ingested, the excess which is infused may be accumulated in some part of the body or it may be randomly stocked in cells here or there or in glands or zones.
When this happens the kundalini energy in those areas may isolatedly burst such that instead of having a spinal arousal, the yogi will experience a gland, zone or bunched area arousal of energy anywhere in the body, in the trunk or limbs or in the entire body.
This energy will be in pixels or micro-pixels, as molecular bursts. It may or may not have a bliss aspect to it. It may be neutral with light sheering limitedly and remaining in the psyche, not protruding it. It may remain concentrated only in the zone where the burst occurred. The yogi may adopt antics and assume unusual postures to facilitate the compression, expression or bursting of this energy.
It may be cool like ice, warm like sunshine in the tropics. It may be cool and warm simultaneously. It may be pleasure yielding which is similar to but different from sexual orgasmic release.
