The reason is that the boundary that limits the will of an individual is the thought of the self. As soon as one has forgotten the thought of self, as soon as one thinks of another, that boundary breaks down and the will becomes stronger. The masters of humanity, those who have been able to do great things in the world, where did they get their will from? It was their own will which was extended by the breaking down of the boundaries of the thought of self. It does not mean that one should give up the thought of self, that one must never think of oneself, never think of one's lunch and dinner. The self is there, one has to think about it. But at the same time in order to expand, in order to let the will grow, the more one forgets oneself the more one is helped.
