Human nature is very much inclined towards what is called intoxication. The reason is that this intoxication gives a man a certain relaxation and temporary comfort. But to gain this comfort and relaxation he depends upon something from outside, and by doing so he becomes a slave to something which is outside himself. I have seen many mystical or spiritual people who practice this experience and they call it ecstasy; it is however not a real ecstasy or intoxication although it may seem to have the same effect, for a real intoxication does not take away one's vitality and it never causes illness. On the contrary, it gives greater health and greater strength; that is why you will always find that the health and strength of a mystic who knows and practices this science are in perfect order.
