Ponder over the contingent realities, their mysteries,
wisdom, connection and relations. The world is harmonious in all things and the
connection therein is mighty and nothing is missing. All things are eaters and
eaten in the physical creation. The plant sucks from the mineral, the animal
eats and swallows the plant, and the human eats the animal. Then the mineral
(in turn) eats the human body. Physical bodies are transferred from death to
death and life to life. Therefore, all things are subject to transfer and
change except the Cause of existence, which cannot be changed or transferred,
because it is the foundation for life in all kinds and species and in all
possible realities in the world of creation.
If thou observest closely through a microscope the water
which man drinks and the air which he breathes, thou wilt see that in every
breath which man breathes, that breath contains numerous animals, and in every
draught of water great number of animals exist. This could not be prevented
because the existent beings are eaters and eaten and, by this, existence is
caused; otherwise, the relations between existent things would cease. When a
thing decomposes and decays, being bereft of life, it becomes promoted to a
world of life greater than the former. For instance, it ceased in a mineral
life and was promoted to the vegetable life; then leaves the vegetable life and
is elevated to that of the animal; then leaving the animal life it advances to
the human, and this is on account of the favor of thy Lord, the Merciful, the
Clement.
