In the spiritual sense, what is ‘past’ has not really passed away but is still there. In physical life men have this conception in regard to Space only. If you stand in front of a tree, then go away and look back at it later on, the tree has not disappeared; it is still there. In the spiritual world it is so in regard to Time. If you experience something at one moment, it has passed away the next so far as physical consciousness is concerned; spiritually conceived, it has not passed away. You can look back at it just as you looked back at the tree. Richard Wagner showed that he had knowledge of this, in the remarkable words: “ Time here becomes Space ”. It is an occult fact that in the spiritual world there are distances which do not come to expression on the physical plane. That an event is past means simply that it is farther away from us. I want you to bear this in mind.
