4524. Now as all and each of the things in the world and its nature come forth, and come forth perpetually, that is, subsist, from things prior to themselves, it follows that they come forth and subsist from a world above nature, which is called the spiritual world; and as in order that they may subsist or perpetually come forth there must be a continuous nexus with that world, it follows that the purer and more interior things which are in nature, and consequently which are in man, are from that world; and also that the purer and more interior things are such forms as can receive the influx. And as there is only one possible fountain of life, as in nature there is only one fountain of light and heat, it is evident that everything of life is from the Lord, who is the First of life. And because this is so, it follows that all and each of the things which are in the spiritual world correspond to Him, and consequently all and each of the things which are in man; for man is a little spiritual world in the least form. Hence also the spiritual man is an image of the Lord.
