Tapas means Austerity
Practice austerity, serious disciplines, penance and sacrifice. Be ardent in worship, meditation and pilgrimage. Atone for misdeeds through prayashchitta (penance), such as 108 prostrations or fasting. Perform self-denial, giving up cherished possessions, money or time. Fulfill severe austerities at special times, under a satguru's guidance, to ignite the inner fires of self-transformation.
