Nadi

Nadi (devanāgarī: नाडी nāḍī) is a Sanskrit term meaning "vein", "nerve" or "tube". In traditional Indian medicine the nadis are the channels through which the life-force known as prana and other energies flow. They connect at special points of intensity called chakras. Amongst these nadis, three are of the utmost importance: suṣumṇā, iḍā, and piṅgala.
