Love is the spirit of life unto the adorned body of mankind, the establisher of true civilization in this mortal world, and the shedder of imperishable glory upon every high-aiming race and nation.
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-BaháThe mind and spirit of man advance when he is tried by suffering. ... so suffering and tribulation free man from the petty affairs of this worldly life until he arrives at a state of complete detachment.
Abdu'l-BaháThere 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.
