“Sushumna runs along the spinal cord in the center, through the seven chakras. When the channels are unblocked by the action of yoga, the energy of kundalini uncoils and rises up the sushumna from the base of the spine.While the sushumna came to be envisioned as a vertical channel extending upwards from the heart, navel region, or base of the torso, there is an old precedent for the idea that it extends, like the śaktitantu, to the feet. The archaic model of sushumna runs from the tips of the big toes to the crown of the head via the navel and heart.” Wikipedia [2]
“The nadis play a role in yoga, as many yogic practices, including shatkarmas, mudras and pranayama, are intended to open and unblock the nadis. The ultimate aim of some yogic practices are to direct prana into the sushumna nadi specifically, enabling kundalini to rise, and thus bring about moksha, or liberation.” Wikipedia[4]
