Selection from Arcana Coelestia ~ Emanuel Swedenborg
In order that good may become good, there must be truths to qualify it. The reason is that when anyone lives according to truths, the truths themselves then become goods; and therefore such as is the quality of the truth, such becomes the good. This good afterward associates and adjoins to itself no other truths than such as are in accord with its own quality, consequently no other than such as are helpful, thus which are in the neighborhood and in the house.
(from Arcana Coelestia 6916)
