“Seth material” search engine (Jane Roberts)

The past, in the present, would appear so brilliantly that man could not react adequately in circumstances of time that he had himself created. The future was blocked, practically speaking (long pause), to preserve freedom of action and to encourage physical exploration, curiosity, and creativity. With memory, however, mental projections into the future were of course also possible so that man could plan his activities in time, and foresee probable results: “Ghost images” of the future probabilities always acted as mental stimuli for physical explorations in all areas, and of all kinds.

These ghost images provided stimuli for mental, spiritual, and physical experience. That answers your question, I believe.

The race was dealing with the creation of a new world of physical experience. To do this particular kind of experiment, it was necessary that physical manipulation be concentrated upon. Ghost images from the future were one thing, inspiring mankind. Had such data instantly appeared before him, however, man would have been deprived of the physical joys, endeavors, and challenges that were so basic to the experiment itself. Do you want to rest your hand?
