The shrine of Malikappurathama is about 100 metres away from the Sannidhanam. Bhasmakkulam/ Ash tank is situated between these two holy spots. Pilgrims braving the arduous trip to Sabarimala take a tip in the sacred waters of this tank for spiritual purification and also in memory of Tapaswini Sabari who entered a pyre to end her mortal life. Sabarimala is named after her. Bhasmakkulam is repeatedly drained and filled with fresh water, on account of the millions who bathe in it.
