force. Every organ, every cell, needs electricity to function. No living cell can function without bio-electricity. The flow of bio-electricity is one type of stream of vital energy called prāṇadhārā by the ancient yoga preceptors.
Our limbs are quite useful, but they cannot be called vital organs. They are workers or soldiers, not regulators or generals. The regulators in our body are: brain, spinal cord, endocrines, bio-electricity, and vital energy. These are the controlling factors-the regulators. From the meditational point of view, it is essential to know them, because through them we can be aware of the entire organism.
The Nervous System
A man is a living organism, but where is the life? Is life in the skin or bones? Is life in blood and flesh ? No, the life is in the nervous system. The life is in the endocrine system. The spinal cord, the brain and the endocrines, are the regulators of all physical, mental and emotional functions.

Spinal cord and the brain compose the Central Nervous System (CNS). Peripheral nerves emanate from the cranium as well as spinal column and branch out in the entire body in the form of an intricate network. The autonomic nervous system controls the functioning of the internal organs. Sensory nerves carry messages to CNS and motor nerves carry orders from the CNS. All the sense organs and mind are connected to the CNS. Intelligence, perception, conceptual planning are the functions of the Central Nervous System. It can be seen from this, that the nervous system is a very important system of the body. If the nervous system fails, the body would be paralysed. There will be neither physical activity, nor mental activity. The endocrine system is the other controlling system of our body.
Both systems are intimately associated with each other and together integrate the organism. The functional interlocking between both qualifies them to be regarded as constituting a single interated system called "neuroendocrine system."
The endocrine glands control the bodily functions through chemical regulators called hormones. They exert
