There are eight ways, two from each place of instruction, one going up in an eastern direction, the other towards the west. Those who come into the Lord's celestial kingdom are introduced by the eastern way, while those who come into the spiritual kingdom are introduced by the western way. The four ways that lead to the Lord's celestial kingdom appear adorned with olive trees and fruit trees of various kinds; but those that lead to the Lord's spiritual kingdom appear adorned with vines and laurels. This is from correspondence, because vines and laurels correspond to the affection of truth and its uses, while olives and fruits correspond to the affection of good and its uses.
