There is much confusion about this reiterated counsel to practise self-surrender, to give up the ego, and to become unselfish. Its primary meaning is not that we are at once to run out in the street and transfer all our possessions to other men. Indeed, it is not concerned with society at all. It is that we are to effect in consciousness a displacement of the lower by the higher self. Such a displacement cannot happen so long as there is any inner resistance on the ego's part. Hence the counsel warns us to avoid such resistance, encourages us to offer the ego willingly as a sacrifice to the Overself, stimulates us to let go of the animal and human complexes which retard the consummation of such a sacrifice. Each struggle passed through successfully builds up our higher will.
