Cultivate the understanding that the self is not really an independently existing entity, and begin to view self instead in terms of it's dependent relation to others. Although it is difficult to say that merely reflecting on this will produce a profound spiritual realization, it will at least have some effect. Your mind will be more open. Something will begin to change within you. Therefore, even in the immediate term there is definitely a positive and beneficial effect in reversing these two attitudes and moving from self-centeredness to other-centeredness, from belief in self existence to belief in dependent origination.
