When thou wishest to treat nervous pains turn thy whole being to the realm on high with thine heart detached from aught else besides Him and thy soul enraptured by the love of God. Then seek confirmation of the Holy Spirit from the Abhá Kingdom, while touching the affected part with utmost love, tenderness and attraction to God. When all these things are combined, be assured that healing will take place. ('Abdu'l-Bahá, The Compilation of Compilations, vol. I, Some Aspects of Heath, Healing, Nutrition and Related Matters)
