I read The Astral City many years ago, and it helped inspire me to learn Astral Projection. The Astral World is very different to the physical world. For example you see by sensing energies, as opposed to trying to look at them. This is not so easy in demonstrate in a film. If you want to know how to visit the Astral City then you will find practical projection techniques at GreatSimulator.com Its good to watch a film such as this because it drives you to explore. One of the best aspects of the whole story is the way in which it makes you realize the importance of learning what lies beyond death. Visiting the Astral World through Astral Projection at least shows you what the reality beyond death is.
