What we want to attain through esoteric exercises is to concentrate completely on one thought and afterwards to let an empty space arise in us and to wait for what flows to us as a result of our meditation. What we attain thereby depends on the intensity of the perseverance that we have applied to this. One might think that one gets ahead faster by changing exercises, but the most profound esoterics have always said that they got the furthest by doing the same exercise with patience and perseverance for years.
