Meditation: Sleep Impulse / Exhaustion Influence
The sleep impulse is given as a negative alert by Patanjali, who listed five such detriments for yoga practice. There is however another related energy which is the exhaustion influence. This one may be mistaken to be part of the sleep impulsive but it is an entirely difference feature within the psyche.
The sleep impulse is collected from ever part of the psyche. In self research, I located it as being stored near the muladhara base chakra, a little to the front of the body near but behind the reproduction apparatus. It takes the form of an oblong capsule. It is grey-brown in color. After a productive rest, this energy is collected slowly and transported from every part of the body, where it arrives near the muladhar base chakra and clings into this capsule form.
Patanjali’s opinion is that it should be eliminated during the meditation session. Using asana postures and breath infusion a yogi may dissolve it where it is reduced in size until it is nil. Then he meditates being free from its influence for the time being. This elimination is temporary because as soon as it is eliminated particularly by doing breath infusion, it begins to be formulated again. Hence before the next session for meditation, a yogi is required to do breath infusion to reduce it to nil again.
The exhaustion energy is different. That is accumulated only from parts of the psyche which were involved in strenuous activity. That could be mental, emotional or physical endeavor but the results will be a feeling of tiredness as if the body should recline and sleep. The exhaustion energy stays in the part of the psyche where it developed as cloudy energy which exudes from the parts which were exerted.
Breath infusion eliminates some but not all of this energy, while breath infusion does reduce to nil the sleep impulse energy. Some of the exhaustion energy can only be removed by resting the body for a time.
