In the universal pattern it is of no importance whether something happens through us or through another person. […] How glad every individual feels that he is capable, that he can do it. A certain resignation is necessary for us to feel equally glad when someone else can and does do something. One should not love something because one has done it oneself, but love it because it is in the world irrespective of whether he or someone else has done it. If we repeatedly ponder this thought it will lead most certainly to selflessness.
