As you know, all Sufis belong to the tradition of Khidr, who is called the green man in the desert, and who appears to the initiates sometimes, a mysterious being who is always present in any real initiation. He is he same person as Elijah, and Elijah is always linked with the water of life. So if you can draw the power of healing from the water of life, from the source of life, that is where your healing will be effective. That is a higher level than the level of the Soul.
