We are in touch with the world by means of sense impressions and with heaven by means of impressions on our rationality.
Sense impressions supply things that serve the inner realms of the mind.
There are sense impressions that feed the understanding and sense impressions that feed the will.
Unless our thought is lifted above the level of our sense impressions, we have very little wisdom. When our thinking rises above sense impressions, it enters a clearer light and eventually comes into the light of heaven. From this light we become aware of things that are flowing down into us from heaven.
The outermost contents of our understanding are earthly information. The outermost contents of our will are sensory pleasures.
