There is but one power which heals—that is God. The state or condition through which the healing takes place is the confidence of the heart. By some this state is reached through pills, powders, and physicians. By others through hygiene, fasting, and prayer. By others through direct perception.

Abdu'l-BaháWhatever other children learn in a year, let Bahá’í children learn in a month. The heart of ‘Abdu’l-Bahá longeth, in its love, to find that Bahá’í young people, each and all, are known throughout the world for their intellectual attainments. There is no question but that they will exert all their efforts, their energies, their sense of pride, to acquire the sciences and arts.
Abdu'l-BaháThe human spirit may be likened to the bounty of the sun shining on a mirror. The body of man, ... grows and develops through the animal spirit.
Abdu'l-BaháThat world beyond is a world of sanctity and radiance; therefore, it is necessary that in this world he should acquire these divine attributes. In that world there is need of spirituality, faith, assurance, the knowledge and love of God. These he must attain in this world so that after his ascension from the earthly to the heavenly Kingdom he shall find all that is needful in that eternal life ready for him.
Abdu'l-Bahá
