According to the yogis, there are two nerve currents in the spinal column, called pingala and ida, and a hollow canal called sushumna running through the spinal cord. at the lower end of the hollow canal is what the yogis call the “lotus of the kundalini”. They describe it as triangular in form, in which, in the symbolical language of the yogis, there is a power called the kundalini, coiled up. When the kundalini awakes, it tries to force a passage through this hollow canal, and it rises step by step, as it were, layer of the mind becomes open and all the different visions and wonderful powers come to the yogi. When it reaches the brain, the yogi is perfectly detached from the body and mind; the soul finds itself free. We know that the spinal cord in composed in a peculiar manner. if we take the figure eight horizontally(∞)there is 2 part which are connected in the middle. suppose you add eight after eight, piled one on top of the other, that will represent the spinal cord. The left is the ida, the right pingala, and that hollow canal which runs through the centre of the spinal cord is the sushumna. Where the spinal cord ends in some of the lumbar vertebrae, a fine fibre issues downwards, and the canal runs up even within that fibre, only much finer. The canal is closed at the lower end, which is situated near what is called the sacral plexus, which, according to modern physiology, is triangular in form. The different plexuses that have their centres in the spinal canal can very well stand for the different “lotuses” of the yogi
Tantric japa yoga start with gayatri japa of activation of internal power first. Activation of internal power centers by gayatri japa yoga.The master of gayatri japa yoga know that words are uttered by different parts of the mouth such as, throat (larynx), tongue, teeth, lips and the root of the tougue.during speech, the nerve-fibers of the particular part of the mouth from which sound emits stretch up to different part of the body and put pressure on the corresponding glands. If particular glands of the person concerted are diseased or dysfunctional, he starts stammering while uttering the specific words. There are many large and small, visible and invisible glands in the body. Yogis know that some specific energies lie hidden in these glands, shat chakaras(six energy centre) related to the sushumana are quite well known but there are several other such glands in the body. His utterance of different words has its impact on different glands and such impact stimulates the energy of these glands. Mantra has been composed on this basis. There are twenty-four letters in gayatri mantra, which are related to twenty-four such glands located in the body, which, on getting stimulated, activate and awaken the power of righteous wisdom. By uttering gayatri mantra the sitar (some thing make musical)of the subtle(sooksham (spiritual body) )body of the sadhak(person who doing japa) stars playing, tinkling at twenty four points, creating sound waves which impact important elements of the invisible world. It is this impact, which becomes more and more pronounced and tangible through gayatri japa yoga.
The flow of sound of these twenty-four letters of the gayatri mantra is of deep significance. The experts of the science of sound know the power hidden in sound and the results, which can be achieved by its subtle vibrations. Sound is synonymous with Brahma(universal energy). It is Brahma from whom the original first creative vibration issues fort resulting in 108-time chating of OM. Just as the pendulum of a clock keeps on moving by swinging to and fro, in the same way the sound waves of OM create vibrations which regulate this creation. And this vibrations respectively flow in this current. It is further divided into branches and sub branches which are known as BEEJA_MANTRA. The letters, words and clauses of gayatri mantra have been seen by a seer vision and emanate from the unified field of creative energy, arranged in a specific and special sequence and inter-relationship. Chanted with sincere devotion, they plug the sadhaks soul into the supreme and inexhaustible fount of spiritual energy.
The vibrations of a specific sound spread in the ether and attract atoms of similar type and return to their origin within few moments, duly charged with appropriate energy which exercises curative impact in the appropriate area. This is how mantras accomplish miraculous effects. The chanting of gayatri mantra activates the network of nerves in the mouth and stimulates specific glands. No sooner do they get stimulated, a vedic symphony is created which spreads in the ether, takes a round of the entire universe, coming back to the source with its energy augmented manifold, capable of fulfilling the desired purpose. Gayatri sadhana. Thus, become a spiritual as well as a material boon for the sadhak.
Gayatri activates the twenty-four divine qualities . With their growth, varied accomplishments.(siddhis) and prosperity start manifesting in the life of the person. Most of the people think that some god or goddess is bestowing these gifts because they are unable to see and understand the working of these subtle divine energies and the transformations flowing therefrom. Once they understand that transformations are taking place as a result of their own sadhana they would realise that it is not by way of some unexpected gift from somewhere but is the result of a well organized scientific process of spiritual growth.
