“A new center – presently dormant in the average man or woman – has to be activated and a more powerful stream of psychic energy must rise into the head from the base of the spine to enable the human consciousness to transcend the normal limits. This is the final phase of the present evolutionary impulse in man. The cerebrospinal system of man has to undergo a radical change, enabling consciousness to transcend the limits of the highest intellect. Here reason yields to intuition and revelation appears to guide the steps of humankind. This mechanism, known as Kundalini, is the real cause of all so-called spiritual and psychic phenomena, the biological basis of evolution and development of personality, the secret origin of all esoteric and occult doctrines, the master key to the unsolved mystery of creation, the inexhaustible source of philosophy, art, and science, and the fountainhead of all religious faiths, past, present and future.
The ancient yogis and sages who developed Kundalini Yoga had a deep respect for the Creator of this human body. They knew, in their profound devotion and worship, that so perfect a Creator could only have created perfection in design, function and potential. Based on this respect, they sought knowledge of the totality of the human being. They researched the human ability to maintain good health, increase vitality, open consciousness and expand the experience of the excellence of human life. Their research gave them a great understanding of the nervous system, glandular system, organ system, energy system, and brain. They learned how blood, nerves, muscles, organds, and glands all work together. They investigated the seen and the unseen, and the inter-relationships between the physical and the subtle. From this research they developed Kundalini Yoga. Kundalini Yoga is a highly evolved technology based on a thorough understanding of the ecology of the human body, how the breath affects the thinking, how the angle of a finger affects the pituitary gland. This technology works with the systems of the human body using the body’s own means. Hand position, breath, posture, sound, and motion are employed in various ways to create the optimum balance among all the body’s components … until recent times these techniques had been secret, taught only to a chosen few.”
“Contemporary spiritual literature often notes that the chakras, as described in the esoteric kundalini documents, bear a strong similarity in location and number to the major endocrine glands, as well as nerve bundles called ganglions. One speculation is that the traditional practices have formalized a method for stimulating the endocrine glands to work in a different mode which has a more direct effect on consciousness, perhaps ultimately by stimulating the release of DMT by the pineal gland, which may be analogous to the 'pineal chakra'. The late Itzhak Bentov studied Kundalini from an engineering perspective. According to Bentov (1990), the 7.5 Hz oscillation of the heart muscle rhythm induces mechanical Hz frequencies in the brain, that in turn create a stimulus equivalent of a current loop. The nerve endings in that loop correspond to the route through which the Kundalini ‘rises.’ This current polarizes the brain part through which it flows in a homogenous way, effectively releasing tremendous amounts of stress from the body. The body then becomes an effective antenna for the 7.5 Hz frequency, which is one of the resonant frequencies of the ionosphere. In layman's terms, you then pick up information from the air. This might account for repeated descriptions of heightened senses as a result of rising Kundalini, e.g. as described by Yogananda: ‘The whole vicinity lay bare before me. My ordinary frontal vision was now changed to a vast spherical sight, simultaneously all-perceptive.’
