The Nadis
The Nadis: Nāḍī (ना ड़ी ) 'tube, pipe, pulse, channel'.
In the most basic sense, Nadis are channels through which vital energy (Prana) flows. They are considered part of the subtle body, distinct from the Physical Body's circulatory and nervous systems.
While some texts mention specific numbers of 72,000 or 350,000 total Nadis, the three main Nadis are Ida, Pingala, and Sushumna, which are associated with specific functions and energy pathways.
One aim of yogic practices, is to direct Prana into the Sushumna Nadi in a balanced way, enabling Kundalini to rise, and thus bring about moksha, or liberation.
