Prana is a
Sanskrit word literally meaning 'life-force' the invisible
bio-energy or vital energy that keeps the body alive and maintains a
state of good health.
Prana is what yogis call the energy known to.the Chinese as
is the key non-physical energy that flows through and around the
body and is responsible for your being alive.
Prana is generally associated with the breath, however the air you breathe is not the actual life-force energy, nor does the air actually contain the prana. Through the yogic practices of asana and pranayama -- movement and breathing techniques -- you utilize the breath to promote, control, and direct the flow of prana.
Yogic tradition states that there are 72,000 energy channels, called nadis, in the energetic body, and that out of this vast number there are three main channels that direct the primary flow of energy through the body. The central energy conduit, the Sushumna, is said to reside within the spinal canal of the physical body. When a person awakens deep spiritual energy, the Sushumna is the channel responsible for containing the flow of this energy from the base of the spine through the crown of the head and often leading the person to experience a state of bliss. The other two main nadis are the Ida and Pingala, which are located on the right and left of the Sushumna. In healthy individuals, prana flows alternately between the two nadis. The Ida is the left side nadi and is said to have a cool, loving, feminine energy. The right side nadi is the Pingala and is said to be associated with heated, intense, masculine energy.
