The tree of knowledge of good and evil

The tree of knowledge of good and evil is the power of discernment by multiple vision, and this is the complete knowing of one’s own nature. Of itself it manifests the magnificence of the Creator and it is good for them that are full-grown and have walked in the contemplation of God for them that have no fear of changing, because in the course of time they have acquired a certain habit of such contemplation.

It is not good, however, for such as are still young and are more greedy in their appetites, who, because of the uncertainty of their perseverance in the true good and because of their not yet being solidly established in their application to the only good, are naturally inclined to be drawn away and distracted by their solicitude for their own bodies.
