While Pingala, associated with energy of the sun, represents the masculine aspect of our personality and is often shown as red. It controls the sympathetic nervous system, and stimulates activities and planning of body and mind. Pingala nadi is responsible for the logical, rational and analytical intellect. Pingala is also the Yang element in Chinese philosophy. When Pingala is overused, due to the hustle and bustle of city life, we can have difficulty sleeping, concentrating or we can become anxious, irritable, and impulsive. Ida and Pingala start and end to the left and to the right of the Sushumna respectively, moving in spirals like the DNA helix, crossing at each chakra or energy portal.
In traditional Chinese medicine, a meridian is a path through which the life-energy or qi flows
The Five Rites of Rejuvenation
The Five Rites are a form of simple stretches that among many things stimulate the gland of the body to increase in vitality and stamina. The Rites are not rigorous exercises. The Five Rites are simple postures that activate the body's nervous system on the etheric level to restore optimal health. The glands are key components in the nervous system. George Crile shows in "The Phenomena of Life" (TPOL) how the glands govern the bodies electrical systems:
Stand erect with arms outstretched. horizontal with the shoulders. Now spin around until you become slightly dizzy. There is only one caution: you must turn from left to right. (Figure 1)
Lie flat on the back on a rug. Then place the hands flat along side the hips. Fingers should be kept close together with the fingertips of each hand turned slightly toward one another. The feet are then raised until the legs are straight up. If possible, let the feet extend back a bit over the body, toward the head but do not let the knees bend. Then slowly lower the feet to the floor and for a moment allow all muscles to relax. Then perform this rite all over again.
Kneel on rug, place hands on things, and lean forward as far as possible with the head inclined so that the chin rests on the chest. Now lean back as far as possible; at the same time the head should be lifted and thrown back as far as it will go. Then bring the head up along with the body. Lean forward again and start the rite all over.
