Prana
According to Hindu yoga teachings, a subtle vitality contained
in the air, modified by the human body to govern essential
functions. In hatha yoga training, this vitality is enhanced
by special yoga exercises known as pranayama. A combination
of hatha yoga exercises and pranayama techniques created a latent
force called kundalini in the body. Reportedly Kundalini
usually supplies energy for sexual activity, but when fully
aroused can be conducted up the human spine to a center in
the head, resulting in higher consciousness or transcendental
states.
Many writers have noted the similarity of teachings on
prana and other teachings concerning subtle energies such as
od or orgone.
