294-295.
Necessity for a Mediator According to 'Abdu'l-Baha:-- A mediator is necessary between man and the Creator--one who receives the full light of the Divine Splendor and radiates it over the human world, as the earth's atmosphere receives and diffuses the warmth of the sun's rays.
If we wish to pray, we must have some object on which to concentrate.

If we turn to God, we must direct our hearts to a certain center.

If man worships God otherwise than through His Manifestation, he must first form a conception of God, and that conception is created by his own mind.

As the finite cannot comprehend the Infinite, so God is not to be comprehended in this fashion.

That which man conceives with his own mind he comprehends.
