Almost no one coming into the other life understands what the blessings and happiness of heaven are, since they do not know what deep-seated joy is or what it feels like. They can grasp it only in relation to bodily and worldly kinds of happiness and joy, and whatever they do not know about they consider worthless. Nevertheless, bodily and worldly thrills are relatively worthless and filthy.
In order for those who are honest but ignorant to learn what heavenly joy is and to come to recognize it, they are introduced first into scenes of Paradise that surpass anything they could ever have imagined. (With the Lord’s divine mercy, these scenes will be described further on [§1622]). They suppose they have now entered the heavenly Paradise, but they are taught that this is not the true happiness of heaven.
Next they experience profound states of joy in their deepest core. Afterward they are carried into a state of peace reaching to the same deep level. They confess that nothing about that peace could ever be captured in word or thought. Finally they are brought into a state of innocence that again reaches right to their deepest level of sensation. This allows them to recognize what true good is like on the spiritual and heavenly planes.
