Subtle Body

If a computer is compared to human composition, then the software that enables the computer to function from within is similar to the subtle body. The battery is comparable to the Pranas or life-force. The Pranas are responsible for all physiological functions, including respiration, excretion, digestion, circulation, sensory perception and thought absorption. Pranayama and other breathing exercises help you maintain your body’s vitality and extend your life. The causal body is the cause from which the subtle and gross bodies emerge. It is understandable from your state of deep sleep. By definition, the causal body or Vasanas, is beginningless, ignorance and inexplicable.
