Frequent reference has been made in previous paragraphs to perception as it existed in the Churches prior to the Flood, and how nowadays perception is something altogether unknown, so unknown that some may imagine it to be a type of continuous revelation, or to be something innate in people. Others may imagine that it is purely a figment of the imagination, and others something different again. But whatever they may think, perception is in fact the celestial itself which the Lord imparts to those who possess faith that inheres in love, and throughout the whole of heaven perception exists in forms endlessly varying. All of this being so, to enable people to have some idea of what perception is, in the Lord's Divine mercy let the nature of the various kinds of perception as they exist in heaven be described later on.
