The Long Healing Prayer

This is one of the special prayers that the Guardian of the Bahá'i Faith, Shoghi Effendi, referred to as having "been invested by Bahá'u'lláh with a special potency and significance, and should therefore be accepted as such and be recited by the believers with unquestioning faith and confidence, that through them they may enter into a much closer communion with God, and identify themselves more fully with His laws and precepts."
It is a powerful supplication to God and is used by many all over the world as profound way to access the many different kinds of healing we need: physical, mental, emotional and spiritual.
