The sushumna is a central energy channel in the body according to yogic and tantric traditions. It runs along the spine, connecting the base of the spine to the crown of the head. This channel is believed to facilitate the flow of spiritual energy, known as kundalini, which can lead to higher states of consciousness when awakened. In the context of chakra systems, the sushumna is flanked by two other channels: the ida and pingala. While the ida is associated with feminine energy and the pingala with masculine energy, the sushumna represents balance and unity. Proper alignment and energy flow through the sushumna are essential for achieving spiritual enlightenment.
