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

I'm interested on what brought you to that conclusion. Personally, my thoughts are mixed. First, it's theoretically possible, but the level of power needed is insane. To do what you're suggesting, you would need to convert your body into energy and resequence it at the point where your body and mind reconnect.

And you couldn't change mid-transit either. If someone interrupted even a small amount of that energy, you would return half-formed, if not worse. Plus, even if it wasn't interrupted, you need large amounts of talent, experience, and knowledge to put your body back together molecule by molecule in a fraction of a microsecond so you don't turn to dust.

So I say, sure.
