When reading about astral projection, I noticed that people describe some processes such as meditation etc, as a way of 'making the astral body float out of the seen body'. In summary, it seems like they are talking of driving the brain into some 'half sleeping' mode. However, what it normally doesn't follow is an explanation as to why such processes can 'release' the astral body. What is it about meditation or sleeping or even dieing that makes the etheric body, astral body or even soul escape from the body? Why can't we astral project or receive telepathic information etc at broad daylight, while fully awake etc just by wishing so or such things?
Here, I want to elaborate on the invisibility of stars at day time, which I have briefly mentioned elsewhere. There are two reasons why stars are invisible during the day time. One is what I may call it 'ganzfeld effect', and the other is what I may call it 'comouflage effect'. If you suddenly move from a place with bright light into a darker room, you will find that the room might at first be so dark that you may not be able to see anything at all. This is the 'gansfeld effect'. Your iris etc have adjusted to bright light by reducing the amount of light the eye can absorb. In the 'camouflage effect', the stars are invisible because of the bright background. During the night, the rest of the sky is dark, leaving the stars as the only bright objects. During the day, the whole of the sky is bright, camouflaging the stars. Both of These effects are caused by the bright sun.
Both these effects can be generalized to observation of everything. This can explain why some things are invisible, even the 'spirits' etc! Infact there is a famous research termed 'ganzfeld experiment' where they scientifically tested if someone can actually send telepathic messages. The basic idea is that if our senses are deprived of external stimulus, our brains will amplify the whatever signal it receives, in the hope of getting even the faintest of the signals. In such a state, the brain might be able to detect otherwise undetectable signals, including the telepathic ones! So it is like locking yourself in a pitch dark room for a long period of time, whereby you will find that your eyesight sensitivity significantly increases. Might you, in such a state, see things that are not even known to exist, e.g. ghosts?
But you must first notice that for this explanation to be truely apt, we must first explain why a 'ghost', an 'aura' a UFO etc might be visible, at least to some people (indeed as long as some people say 'they see' these things there must be some scientific explanation as to what went on in the retina etc). Specifically, in our case, the invisibility of auras, UFOs etc must be due to the fact that they emit a too dim light. So the physics at work in emmitance or reflection of that light will be the same physics at work in the observation of ordinary objects! This is what we must swallow for the claim that some people can see UFOs etc to have some credibility! The light must have bounced off the object, and so the object can interact with the electromagnetism in a way a physicist can explain! This is not 'immaterial' at all!
In the case of astral projection, it is a bit more tricky. This is because astral projection is not about seeing an object from remote. It is about being the very object that is invisible to the ordinary senses. The idea that I use is that we can always feel that we are out of our body but the fact that our seen body is at wake, we will always feel as if we are in the seen body. So we cannot experience ourselves in say the 'empty space' because the experience of ourselves inside the seen body eclipses the experience of ourselves inside the other body! This seems at first to be problematic since it seems to demand two 'selfs'. In the one 'self', we have our senses helping us the experience the other 'self'! So when the other 'self' is 'too bright', the senses belonging to the first 'self ' suffers from the ganzfeld effect! So which 'self' is the true 'self'?
The answer is that we are realy not one! We are many! For instance, our brain is composed of many cells. When one cell observs another cell, it appears to us like 'being aware of our own selves'. So we might consider our invisible 'parts of our brains' that exists beyond the seen brain. Just as the many cells of our brains still manifests the same single awareness, even addition of more cells can still be the same awareness! So our brains could be as big as the whole earth, but still the farthest portion experiences itself as one with the portion at the other end! In other words if we had the brain as big as jupiter, we would still feel like a single being inside such a brain. But if one eye was at the farthest point, then closing one eye and then opening the other would be like moving from one end of the planet to the other in a twinkle of an eye! We would immediately see the things at the farthest end. But all this is because the thus huge brain still manifests the same single awareness.
This now offers a different way of understanding astral projection. We can astral project because our brains actually doesn't end where they appear to end. They extend throughout the whole universe! This unseen 'brain' has all its portion interconnected with the rest portions. So the signals received from one part is communicated to all the other parts. If the signals received from the seen body is 'too bright', the rest of the 'brain' experiences the 'ganzfeld effect' because the signal from the bright portion is fed to the rest. Then the information that those other portions could have obtained get dimmed accordingly, creating the impression that the seen body is the only source of information. So incase the brain in Jupiter receives more information, you might begine to experience the things in Jupiter, seeming like 'you have gone all the way to Jupiter in a twinkle of an eye'. After all who knows what happens if we get teleported to a distant place? We don't seem to go there at all. Rather, the place itself seems to 'come' to our place, like the way the sun seems to move when the earth is the one moving. This 'moving without realizing that we are miving' is no different from just staying on the spot and obtaining all the information pertaining to that place so that it seems like you are staring at that place head on! So communication is equivalent to movement! With this, we can understand astral projection in a different way, where we don't realy move at all. We just keep obtaining information pertaining to different places one at a time, and the 'movement from one of those places to the other' is just illusory! What actually happens is that 'we are at all those places all at once' since our 'brain' is so big that it covers all those places, but we don't experience ourselves in all those places all at once due to ganzfeld effect!
