Through systematic exercising of our thinking faculties, we can train ourselves for exact clairvoyance. Imaginative Knowledge is the first step in supersensible perception, and through it we reach the first element of the supersensible it is possible to reach, namely, the supersensible body that we bear within our earthly body in physical space.
If you observe children with sufficient objectivity as they grow into the world, then you will perceive that children's temporal bodies are still not fully connected with the spirit-soul.
