An unlimited resource of electrical energy forms the basis of physical manifestation of Nature. The discovery of this fact and persistent efforts to utilize this immense power of Nature has been of great help in scientific and technological developments of our age. The space between the earths strata and the Ionosphere contains positive potential of about 3 X 105 volts while the earths interior contains an equivalent amount of negative charge. On an average, every living organism on the earth bears a subtle electrical pressure of the order of 5 volts/m created by the lowest layer of the Ionosphere situated about 60 km above the earths surface. This potential generates an electric current in human body, which is a good conductor of electricity. The measurements by sophisticated instruments have shown that this current is of the magnitude of 10-16 Amp Sec/cm2. At a first glance, this small quantity of current may appear to be negligible. Nevertheless, its effects are incredible because of the existence of some subtle power centers in the human-body as described below. The scientific exposition presented here is focused on the subtle power centers in human-body whose existence is manifested in the forms of Bioelectricity and Biomagnetism. The subtle bioelectrical energy provides the vital force for the bodys functioning and governs various mental activities. Human body simulates an Ocean consisting of infinitely many rivers in the form of the Blood vessels and the Nerves. Each respiratory cycle gives rise to high and low tides of currents in this Ocean at an average rate of about 15 cycles/minute. The technique of electric power generation from the tides and cyclones in the seawater is well known today. However, very few people know that the electric ions inhaled from the surrounding atmosphere during each respiratory cycle give rise to a powerful tide and hence electrical flow within our body. The ancient Indian sages (Rishis) had a deep knowledge about this current and its utilization for higher purposes. Our body can be likened to a grand powerhouse. The brain and the heart work respectively like the generator and the transmitter of the bioelectricity (ionic currents) in the body. The bioelectric energy is distributed amongst the body cells as per their functional requirements. This electricity, in conjunction with the (subtle) vital energy of a person, produces the (bio) magnetism which in turn manifests as the aura ( halo of light ) around ones body and the region of attraction in ones personality. It should be noted here that biomagnetism is a consciousness-power which can affect the material as well as the conscious forms existing in Nature. If this subtle vital energy could ever be measured as an electromagnetic energy, it would turn out to be the greatest gift of the Creator of the Universe to the human race. The spiritual seers and sages of yore had found that the presence of this biomagnetism could be experienced by personal contacts, communication or meditation. Supernatural abilities can also be developed by controlling and channelising this energy through different spiritual practices. This energy then also helps in communicating with the subtle realms of consciousness pervading the universe. The individual consciousness (individual self) is a part of the Omnipresent Supreme Consciousness Force and the extent of the manifestation of the latter via sentiments, thoughts and deeds of the former depends on the level of above mentioned biomagnetic (vital) energy. The subtle energy is an integral part of all the cellular and molecular constituents of the body. Its physical existence in all the cells, tissues, neurons, enzymes, glands etc. is as homogeneous as that of the dissolved salt in the seawater. The overall intelligence, vigor and energetic alacrity, (collectively called ojas) of a person is maintained by this vital energy. This subtle energy also inspires the radiance (tejas) of thoughts and the divinity (varchas) of the inner self (antahkarana).
