“The Tariqat-an-Naqshbandiyya, (as it is passed down through Abu Bakr As-Siddiq), activates the souls of the murids to whatever extent the murid can bring his desires to accord with the desires of his Sheikh. So many murids have high spiritual aspiration (Himma) and they say: ‘Oh my Sheikh, I am asking for himma in order that my soul be activated.’ The Sheikh replies: ‘Oh my son, I am asking service from you (Khidma). What is this service? You must be like me; when you are like me, my spiritual powers may come to you, but if we are not of the same kind of metal, the current can’t pass through you: I am copper, you must not remain stone.’”
