In discipleship one has to consider the idea of sympathy. The great Lord of yoga, Mahadevi, warned against initiating or welcoming an insincere, ungrateful, or doubting pupil into the mystical cult. This was his advice to every mystic. Why was this? What concern is it of the mystic whether a pupil is grateful or not, sincere or not, as surely he has to be good to everyone? The idea is that unless a person is sincere he is not ready to benefit, and the teacher will not do him any good. He must have sincerity and faith and sympathy. How true is the saying, "He who speaks evil of another knows him not; he who speaks well of another knows him better'! This illustrates the fact that sympathy is the only thing that discloses the secret of all things.
