I remember the blessing my spiritual teacher, my murshid, used to give me every time I parted from him. And that blessing was, "May your Iman be strengthened." At that time I had not thought about the word Iman; on the contrary I thought as a young man, is my faith so weak that my teacher requires it to be stronger? I would have preferred it if he had said, may you become illuminated, or may your powers be great, or may your influence spread, or may you rise higher and higher, or become perfect. But this simple thing, may your faith be strengthened, what did it mean? I did not criticize but I pondered and pondered upon the subject. And in the end I came to realize that no blessing is more valuable and important than this. For every attached to a conviction. Where there is no conviction there is nothing. The secret of healing, the mystery of evolving, the power of all attainments, and the way to spiritual realization, all come from the strengthening of that belief which is a conviction, so that nothing can ever change it.
