Illnesses which occur because of physical causes should be treated by doctors with medical remedies; those which are due to spiritual causes disappear through spiritual means. Thus an illness caused by affliction, fear, nervous impressions, will be healed more effectively by spiritual rather than physical treatment. Hence, both kinds of treatment should be followed; they are not contradictory.

All down the ages we see how blood has stained the surface of the earth; but now a ray of greater light has come, man's intelligence is greater, spirituality is beginning to grow, and a time is surely coming when the religions of the world will be at peace. ...let us join together to hasten forward the Divine Cause of unity, until all humanity knows itself to be one family, joined together in love.

It is your duty to be exceedingly kind to every human being...until ye change the world of man into the world of God.

Never is it the wish of `Abdu'l-Bahá to see any being hurt, nor will He make anyone to grieve; for man can receive no greater gift than this, that he rejoice another's heart. I beg of God that ye will be bringers of joy, even as are the angels in Heaven.

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.

By nothing,under no conditions, be ye perturbed.

The reality of man is his thought, not his material body. The thought force and the animal force are partners. Although man is part of the animal creation, he possesses a power of thought superior to all other created beings.
