3562. 'And he felt him' means complete perception. This is clear from the meaning of 'feeling' as inmost and complete perception, dealt with above in 3528, 3559, here complete perception because the perception of all things comes from inmost perception. That is, people who possess inmost perception possess a perception of everything that is below, for the things that are below are nothing else than derivatives and combinations of what is above. Indeed everything inmost exists in all the things below it that are its own, for unless that which is lower is the product of the things that are interior, or what amounts to the same, of those that are above it, as an effect is the product of its efficient cause, it does not come into existence at all. From this it is evident why the end in view determines a person's happiness or unhappiness in the next life, for the end is the inmost aspect of every cause, so much so that if the end does not exist within the cause, indeed if it is not its all, no cause exists at all. The end is in a similar way the inmost aspect of every effect, for an effect springs from such a cause. This being so, whatever exists with a person owes its very being (esse) to the end which he has in view. In the next life therefore a person's state is determined by the essential nature of whatever end he has in view, see 1317, 1568, 1571, 1645, 1909, 3425. From this it may be seen that, since it means inmost perception, 'feeling' consequently means complete perception.

536. 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.
