With regard to your question concerning spiritual healing:
Such a healing constitutes, indeed, one of the most effective methods of relieving
a person from either his mental or physical pains and sufferings. 'Abdu'l-Bahá
has in His "Paris Talks" emphasized its importance by stating that it
should be used as an essential means for effecting a complete physical cure.
Spiritual healing, however, is not and cannot be a substitute for material
healing, but it is a most valuable adjunct to it. Both are, indeed, essential
and complementary.
