Thoughts On Teleporting, via astral projection Options

This hasn't really formulated in my mind enough yet to become a theory, so it's more just a jumble of thoughts I wanted to get some input on. I came across a few theories in various sources where people believed that someone could teleport physically with enough practice by astral projecting and then pulling their physical body to them. I also came across a website while researching something completely unrelated - that is, underground tunnels in cities that gangs used for fast escapes. I found a lot of information speculating the existance of some underground tunnels in San Fransisco, although they were never found after the gigantuous earthquake. As to the original point, theres a theory that the tunnels didnt physically exist, but there were secret rooms with certain metals and gemstones used for conducting enough energy to teleport out, using some magical laws of chinese alchemy. Site is here if you want to read the less scattered summary:

ANYWAY, I'm just wondering if anyone thinks this would be possible, or the theory of summoning your body to you with astral projection has any possibilities. Also, I know a lot of people agree with the concept of astrally travelling in time on the spiritual plane. If one's able to teleport through astral projection, in theory it would also be possible to pull your body through time, therefore time travelling physically. Pretty sketchorific stuff. Not sure what my opinions are on any of this, but any others are welcome. Thanks

PS - Not sure if this belongs in this forum, so move if it should be elsewhere

Teleportation, imo, is just another word for transportation. Essentially the astral body is a vehicle built from will and powered by the physical body that transports the mind of an indiviudal in alternate plains of existance. If you rewrote that sentance with the word teleportation in place of transportation it'd mean just about the same thing. Even more so in how travel actually works in the astral realm. At least for me, when I move in an astral state I basically just pop up in one place or another. Generally I also fly or float but even then travel tends to be very fast for me. Only if I willfully slow myself down and litterally anchor myself to a spot do I ever walk in my astral surroundings. I'm sure there have been acceptions though.

You mentioned travel through space in time. From my experience the laws of physics sort of blend together and have no real meaning beyond personal perception and observance of them. Thus one could easily travel through time and space. The limmitation I see is in experience. A more practiced individual will be able to remain in an astral state longer than a novice. Thus they would be able to travel farther - understand this doesn't mean travel in litteral distance, rather in time. The longer one is in the astral plains the more they will see and experience thus the greater distance they will have gone. As far as traveling through time itself its really immaterial because time in the AP moves in all directions.

Key point in mind, imo, is that space and time are subjective in the astral plains, almost as if the laws of physics there are inverted, no real gravity, space is limmitless and endless, time moves in all directions. Perhaps the idea that this unvierse coexists with another opposite to this one is actually right. Our simple minds have just doubed it the astral plains.
