This asana is a variation of
paschimottanasana (seated forward bend), a resting stretch,
but adding the mild twist stimulates the spine. As a forward bend, it
calms the nervous system and the mind. As a twist, it activates the
manipura (solar plexus or navel) chakra. This chakra is the body's energy and
vitality center, and opening it through this posture is believed to
dispel fear and insecurity. Manipura is associated with
self-esteem, self-confidence and a sense of purpose.
Parivrtta paschimottanasana is also
a grounding asna. As such, it activates the muladhara (root) chakra,
which provides a sense of stability and security. Opening muladhara also sets the foundation for activating the other chakras.
