"..(Healing results) from the entire concentration of the mind of a strong person upon a sick person, when the latter expects with all his concentrated faith that a cure will be effected from the spiritual power of the strong person, to such an extent that there will be a cordial connection between the strong person and the invalid. The strong person makes every effort to cure the sick patient, and the sick patient is then sure of receiving a cure. From the effect of these mental impressions and excitement of the nerves is produced, and this impression and this excitement of the nerves will become the cause of the recovery of the sick person." ('Abdul-Baha - Saq p 294) (108:3)
