A Proper Understanding of the Active/Passive Aspect - pg 5
The Active and Passive Aspects of Each Kundalini Yoga Exercise: Finally, it is vitally important to understand that each Kundalini Yoga exercise has an active part and a passive part. In other yogas this is not the case; each posture is a complete exercise in itself, whatever the series might be or whether in a series (like a karate karta) or single posture to corpse pose.
But in Kundalini Yoga the purpose of the practice is to develop radiance (laya) and depth (pratyahar), which is only felt in other yogas much further along in their practice. In Kundalini Yoga you are maximizing and working directly with all the systems of the body simultaneously – circulatory, pulmonary, endocrine, nervous etc. Each posture and movement brings about a pressure in a specific area or system of the body. This pressure means that the blood will saturate in that area. As powerful Kundalini Yoga breathing techniques are combined with the postures and movements, these areas being put under pressure will have the strong effect of the purified and energized blood flow into that area. Initially, this means that these areas, where the capillaries and cells open under the pressure of the exercise, discharge their impurities and toxins in return for the vitality of the purified energized blood flow. Moreover, these same areas begin to build a charge - a voltage.
Now, here is the important part to remember: The body is like a car battery, only with many batteries working together. In a car battery there is water and there are chemicals. As the chemicals are increased the voltage of the battery also increases - 3 volts, 6 volts, 12 volts, 24 volts (standards we can buy at any K- Mart. The body is mostly water, with some chemicals whose secretion is the basis for the maintaining of voltage generated in the body. This is why it is said: You are as young as your glands. In the practice of other yogas, there is a gradual process in which the tensions and blockages of the body are reduced and the mind begins to become still. The process accelerates with increased practice and especially fasting and internal purification, such as (in the west) colonics (versus Nauli Kriya for cleaning the large intestine). Then, as the energies of the body are used less and less towards the incessant pressure of thinking and identity encoding, imaging, impression taking and so on, there is a build up of unused kinetic energy that begins to fill through the body so that the body begins to lose its inertia, becoming satvic (pure), transparent and blissful easing into the ever-present oneness of the yogi's surrounding. In other yoga practices, awareness to movement and eventually prana is a key to the expansion of this kinetic energy. In Buddhist meditation and martial arts, it is called "Mindfulness." This is because that simple awareness through which we experience the inner and outer world is really the light of the Infinite Being.
In Kundalini Yoga, the posture/movement (always practiced with still awareness) combined with powerful breath creates this purification in various areas of the body directly and with it comes an electrical charge to these areas. To support this electrical charge, the glands secrete very specialized chemicals. The charge or voltage generated directly impacts the glandular system causing the glands to secrete so that this charge may be sustained and maintained. Chemical electric pathways open. Once the active part of the Kundalini Yoga exercise is completed, the passive part begins. The reaction of the glandular and nervous system to the vitality of the bloodstream impacting the specific areas of pressure brought about through the posture or movement takes some time to complete. The time period depends on the duration of the exercise and other dynamics of the body's ability to circulate the secreted chemicals. Therefore, you have an active aspect of each Kundalini Yoga exercise and a passive aspect, which must be experienced for the exercise to achieve its full benefit!
In experience of the passive aspect of a Kundalini Yoga exercise, there is the sensation of decontraction of the cells, muscles and ligaments in the area. Then comes the sensation of opening and radiance. The radiance begins to balance with all other organs and cells, strengthening the magnetic field of the whole body, bringing it into balance with the area affected in the exercise. Through each progressing Kundalini Yoga exercise and kriya, you begin to feel a previously impalpable sensation of "electric radiance"/"transparent electric", which grows expands and brings about a deepening. At the end of each set, usually before a meditation, we allow the body to go into a deep relaxation, yoga nidra. With deep relaxation, all the energies compacted in various areas of the body may finally release, merge,deepen, effecting an entire systemic new increased voltage plateau in the body, so that gradually you will become aware of the inner and outer radiance continuously.
In Kundalini Yoga, we usually diversify the sets practiced in order to bring about the opening of the cells, glands, organs, nerves and systems in every area of the body. Typically, the passive part of a Kundalini Yoga exercise is as long as the active part, but what you are looking for is a sensation of the radiance circulating and rising through the body to the crown and beyond, which indicates the balancing of the electromagnetic field is complete.
Typically the Yoga Nidra is 10 to 15 minutes.
Purification of the subconscious:
The body is a mechanism that stores the impressions of who we think we are. (The body is like the hard drive for computer storage, versus the brain as the RAM/cache storage.) Because the impressions are stored in the body structure, we call it the subconscious. With Kundalini Yoga practice, the electric chemical balance of the voltage of the body increases to bring about a system wide vibratory frequency that is higher – more subtle – than the frequency of thought vibration, so that your sense of identity begins to become clearer and clearer, less linked to thought and sensation. No longer drawn to this or that reactive thought or imbedded compulsion, but open single clear awareness of the pervasiveness of consciousness throughout the body field (i.e., the ten bodies).
At the lower voltage level of the body, the mind's focusing mechanism of attention needs to be used to see and know. It moves through the darkness (unawareness) of the body/mind field like a flashlight used to see on a dark night whose light grips each arising thought, sensation, impression in order to compare or merge with the sense of "I" inherent in the light. Sometimes more is seen. Like the waxing and waning of the moon cycles, the mind becomes brighter (feelings of love, compassion – satvic) and dimmer (feelings of hate, distrust, judgment – rajasic, tamasic).
