This is from Abdu’l-Baha, from book “Paris talks” His talks are made into book.
“God contains all: He cannot be contained. That which contains is superior to that which is contained. The whole is greater than its parts.
Things which are understood by men cannot be outside their capacity for understanding, so that it is impossible for the heart of man to comprehend the nature of the Majesty of God. Our imagination can only picture that which it is able to create.
The power of understanding differs in degree in the various kingdoms of creation. The mineral, vegetable, and animal realms are each incapable of understanding any creation beyond their own. The mineral cannot imagine the growing power of the plant. The tree cannot understand the power of movement in the animal, neither can it comprehend what it would mean to possess sight, hearing or the sense of smell. These all belong to phyisical creation.
Man also shares in this creation; but it is not possible for either of the lower kingdoms to understand that which takes place in the mind of man. The anima cannot realize the intelligence of a human being, he only knows that which is percieved by his animal senses, he cannot imagine anything in the abstract. An animal could not learn that the world is round, that the earth revolves round the sun, or the construction of the electric telegraph. These things are only possible to man. Man is the highest work of creation, the nearest to God of all creatures.
All superior kingdoms are incomprehensible to the inferior; how therefore could it be possible that the creature, man, should understand the almighty Creator of all?
That which we imagine. is not the Reality of God; He, the Unknowable, the Unthinkable, is far beyond the highest conception of man.”
