Janu Sirsana comes from the Sanskrit root words janu, meaning “knee,” sirsa, meaning “head,” and asana, meaning "pose."
Like many forward bends, janu sirsasana B is considered a restorative pose because of its calming effect. It is also said to re-energize the body while the pressure of the heel generates therapeutic heat.
This posture can be used to help students connect with themselves. Due to the introspective nature of the posture, janu sirsasana can be a good place to practice svadyaha, or self study, helping the practitioner to experience more awareness and connection with the inner self.
It can also be a good posture for letting go and clearing any emotional attachment as one releases into the forward bend. Some say that powerful emotions or fears are stored in the base of the spine and these can be cleared through consciously surrendering into janu sirsasana.
Janu sirsasana is said to help activate and balance the muladhara chakra as it can release any tension held in the legs or lower abdomen. It is also associated with stimulating the bladder meridian in Chinese medicine, which helps us to manage change in life.
