It's interesting Naruto,
I have just read through a long list of messages in the psi forum and noted that many people experienced what Mike describes, it is certainly not him only that experienced that. One even blacked out with the experience, and gave up doing tk as a result
As to drawing on internal power. yeah, that is where it starts.. but without fail I noticed that , once you try one thing you want to move onto something else. You get taught how to manipulate other things.. the small things become inadequate and the big things start to interest..
Can you tell where "your" powers end and those other powers that mike talks of begin?
I think not. The subtle reality is.. you are projecting so much of yourself into what you are doing in psionics, you lose contact with reality, so you cannot even begin to know when other powers are taking over.
I know this might sound absurd but look back over the posts in the psi forums again, and this time do it not with the eyes of a participant, but the eyes of one looking for signs of when the demonic comes.. you will find them everywhere, and I'm happy to look through them with you if you want.
