The elder warned us not to pray while our hearts were steeped in unprayerful feelings, without thoughts wandering as they chose. Prayer is not a mechanical activity, but a confrontation, a conversation with the Holy Presence. Pray humbly, then, in awe of God.
Notice that the more you become a connoisseur of gratitude, the less you are the victim of resentment, depression, and despair. Gratitude will act as an elixir that will gradually dissolve the hard shell of your ego -- your need to possess and control -- and transform you into a generous being. The sense of gratitude produces true spiritual alchemy, makes us magnanimous -- large-souled.
