" Gnan (knowledge) is a light. If you do penance after attaining that light, then you will attain liberation (moksha). And with this agnan tapa (penance in the absence of Self-Knowledge) you will acquire the body. The reward of mental penance is worldly in nature. One will receive the fruit for enduring the heat of the penance. "
