In a talk with Miss Ethel Rosenberg, in October 1904, 'Abdu'l-Baha said:
The healing that is by the power of the Holy Spirit needs no special concentration or contact. It is through the wish or desire and the prayer of the holy person. The one who is sick may be in the East and the healer in the West, and they may not have been acquainted with each other, but as soon as that holy person turns his heart to God and begins to pray, the sick one is healed. This is a gift belonging to the Holy Manifestations and those who are in the highest station. (73:1)
