Ida & Pingala

Nadis are not nerves but rather channels for the flow of consciousness. The word nadi comes from the Sanskrit root nad meaning "channel", "stream", or "flow". Just as the negative and positive forces of electricity flow through complex circuits, in the same way, prana shako (vital force) and manas shako (mental force) flow through every part of our body via these nadis. According to the tantras there are 72,000 or more such channels or networks through which the stimuli flow like an electric current from one point to another.

In particular prana (active) is supposed to circulate inside Pingala, while apana (passive) is supposed to circulate inside Ida. Inside Sushumna is supposed to circulate kundalini when awakened.[3] The Ida and Pingala nadis are often seen as referring to the two hemispheres of the brain. Pingala is the extroverted (Active), solar nadi, and corresponds to the right hand side of the body and the left hand side of the brain. Ida is the introverted, lunar nadi, and corresponds to the left hand side of the body and the right hand side of the brain (there is a contralateralization).

Chakra is the power center associated with the subtle body of man. Each chakra is ruled by an incarnation of Goddess Parashakti.
