Through discriminative self analysis and logical thinking one should separate the Pure Self within the sheaths as one separates the rice from the husk, bran, etc., that are covering it. (Atma Bodha Verse 16)

Sons and others are capable of taking care of a father’s debts, but no one except oneself can remove his own bondage.
