Know nature and spirit both (to be) without beginning, and know all developments and qualities (to be) produced from nature. Nature is said to be the origin of the capacity of working (residing) in the body and the senses; and spirit is said (to be) the origin of the capacity of enjoying pleasures and pains. For spirit with nature joined, enjoys the qualities born of nature. And the cause of its birth in good or evil wombs is the connexion with the qualities.
