Mike Dooley's 'Question...?' in the Ask Robert forum
viewtopic.php?f=28&t=12311

1. A couple of years back I had a conversation with this guy about Astral Projection. He kept telling me that in order to get to the Astral World once I was out, I had to find a tube. He said that these so-called tubes would take me to where I wanted to go.
There are many ways to get to the astral from the RTZ, and the tube or vortex is just one of them. They consist in: Gateways from Reality fluctuations, that is doors or windows that are put there by your own subconscious (see 'Alice in Wonderland' in Robert's Treatise, Going through a mirror (realtime), and one Robert talks about in Astral Dynamics, which is flying up fast, and then either appearing on a plane or flying up and looking back down to the planes proper.
You can also use Mystic projection which is keeping your attention on a spot on your energy body and expressing the desire to go there. Spots on your energy body can correspond to Sephiroth in Kabala which can also correspond to specific places in the astral. Aunt Clair has info on this if it interests you, but it is a subject for study in and of itself.

2. He also told me this story about a Megatron. He said that it was this big machine that he used to talk to someone out in California. I thought Megatron was the silver guy from the Transformers.
I have heard of this (here in this forum) by people trying to sell them. I strongly suspect anything like that, and consider it to be possibly even dangerous, because like a ouija board, it can open you to invasion if it works. I wouldn't mess with that if I were you. But that's my opinion.
