Selection from Arcana Cœlestia ~ Emanuel Swedenborg
Truths are said to be impressed on the life, when they become of the will and from this of the act. So long as they stay merely in the memory, and so long as they are looked at only intellectually, they have not been impressed on the life; but as soon as they are received in the will, they become of the life, because the very being of man's life is to will, and from this to act; and before this they have not been appropriated to the man.
(from Arcana Cœlestia 9386)
