While it is always well to learn everything one can, it is not good to give in to superstition. Otherwise it would be better never to have known such things at all. The whole aim of the Sufi is to reach to reality, and anything savoring of superstition should be avoided. What is color after all? It is an illusion. What is number? It is an illusion. What are forms? They are illusions too. It is interesting to a certain extent to know about these things and to distinguish them. It gives a certain knowledge. But since these are all illusions, how can it be worthwhile to give oneself absolutely to them and to neglect the unfolding of the self, besides at the same time neglecting the search for the reality, the only aim of the soul? Therefore all other knowledge and all other pursuits should be given a secondary place. Our main pursuit must be after Truth, believing as we do that in the Truth there is God.
