Afterwards I asked those spirits about various things on the planet from which they came. First I asked about their worship of God. To this they replied that every thirtieth day the clans and their families gather together in one particular place, where they hear sermons. The preacher then, speaking from a platform raised somewhat above the ground, teaches them truths from God which lead to goodness of life. When asked where their knowledge of God's truths came from, they said, From revelation. And of revelation they said that it takes place in the morning, in the half-way state between sleep and wakefulness, when they are in an inner light into which no sensation in their physical body nor any perception of worldly objects has as yet intruded, and when they hear the angels of heaven talking about God's truths and about a life in accord with them. And when they become fully awake there appears to them at their bed an angel in a white robe, who then suddenly disappears from their eyes. From this they know that the things they have heard come from heaven. This is how a vision from God is distinguished from a vision that does not come from God, for no angel appears when the vision does not come from God. They added that this is the manner in which revelations are made to their preachers, and sometimes also to others.
