'The second river', which is called the Gihon, means the cognizance of all things that have to do with what is good and what is true, that is, with love and faith. 'The land of Cush' means the mind, or [mental] power. The mind consists of will and understanding. All that is said about the first river has reference to the will, and all that is said about this [second river] has reference to the understanding, to which the cognitions of good and of truth belong.
