Man too has to pay his debts. He is heavily indebted to God for all the good, the true and the beautiful, with which he is endowed. He must pay the debt he incurs when he hears a discourse; this is done by ruminating over what has been told and practicing at least a few of the ways of life that have been recommended. The meal that is eaten has to be digested, so that it may strengthen the bloodstream and transform itself into courage, skill and stamina.
(SSS Vol IX – Chap 26)
