“The less a person carries, the easier it is for him to climb and the higher he is able to climb. So, too, in order to ascend spiritually, it is necessary first of all to free oneself from the weight of sin. This weight is lifted from us through repentance, provided that we banish from ourselves all enmity and forgive each person whom we consider to be at fault before us “
(St John of San Francisco,   ‘Selected Sermons’)
