By reading the human mind a mystic gets insight into human nature and to him the life of human beings begins to appear as a mechanism working. The mystic learns from this that life is give and take. It is not only that one receives what one gives but also one gives what one receives. In this way the mystic begins to see the balance of life; he realizes that life is a balance, and if the gain or loss, the joy or pain of one outweighs that of another, it is for the moment, but in time it all sums up in a balance, and without balance there is no existence possible.
