„Your SPINE is your Body BATTERY. Keep it CHARGED.” Paramahansa Yogananda, Autobiography of a Yogi
Swami Bodhichitananda explains in this video the 39 energization exercises from the Kriya Yoga lineage of Paramahansa Yogananda. Yogananda developed them to bring more Prana into the system. He said that the Prana and the breath is connected to the heart and to the mind.
“Kriya Yoga is a simple, psychophysiological method by which human blood is decarbonated and recharged with oxygen. The atoms of this extra oxygen are transmuted into life current to rejuvenate the brain and spinal centres. By stopping the accumulation of venous blood, the yogi is able to lessen or prevent the decay of tissues.”
“Every religious or philosophical practice means a psychological discipline, that is, a method of mental hygiene. The manifold, purely bodily procedures of Yoga also mean a physiological hygiene which is superior to ordinary gymnastics and breathing exercises, inasmuch as it is not merely mechanistic and scientific, but also philosophical; in its training of the parts of the body, it unites them with the whole of the spirit, as is quite clear, for instance, in the Pranayama exercises where Prana is both the breath and the universal dynamics of the cosmos…. “Yoga practice…would be ineffectual without the concepts on which Yoga is based. It combines the bodily and the spiritual in an extraordinarily complete way. “In the East, where these ideas and practices have developed, and where for several thousand years an unbroken tradition has created the necessary spiritual foundations, Yoga is, as I can readily believe, the perfect and appropriate method of fusing body and mind together so that they form a unity which is scarcely to be questioned. This unity creates a psychological disposition which makes possible intuitions that transcend consciousness.”
