I agree Lia with Justin's (ahso) explanation. For years like Bruce, I tried for the full blown obe. I did have maybe a half dozen, but they were not under my conscious control except for one was.
To discover the phasing is definetely under your control although it's not as the same feeling of being in another space of reality as the full blown obe, it's more for me, like observing myself walking or gliding or interacting with others, like scenes, where I have a form, but I'm watching the movie from above, although there can be sight, hearing, sense of touch, scent, which always lends an air of being grounded there also.
In the involuntary obes (not seeming to be my origin but were) I could never go fly unless I had the right "question." Or, the right motive, according to my highest growth intelligence, I'll call it.
Meaning, if the experience I desired would do me good, or do someone else good, this is coming from the higher perspective Justin mentioned, the higher vibrational pathways of mind.
every obe, or phasing, is different. None would be repeated quite the same, so there was no way to have it be reliable, unless some sort of prayer, emotion was involved. In other words, my higher self just wouldn't let me go out for fun, just to prove I could.
there are books explain you can do this by depriving yourself of water. Then supposedly, you are so thirsty, your astral body gets up and goes to the kitchen for a drink. I could see this would work, as I had an obe as a kid, and the body needed to go to the restroom, and so my astral got up and went and every movement felt exactly as it would in physical area.
however, I don't believe in techniques like this for myself, not after a couple of phasing experiences on a higher level. I'm a little leary of making myself thirsty....just for an obe.
You could ask for a guide. I asked for one and you don't always see them but you might sense some help nearby and trust that. this particular time I asked to do a retrieval, but only if necessary. I didn't go obe, but I saw a face in front of my 3rd eye and that was a retrieval to perform and it was also the same thing as phasing I surmise. I began to interact with the face which turned into a man's form.
it was just as satisfying an experience as the full blown obe, just very different. Since we are all unique, Lia, you will have your experiences in the way that is best suited for you, according to your higher self.
You will probably have some full blown ones, then later some phasing ones if you follow the normal patterns how we develop.
Vicki, I was given some laughing gas once. I kept waiting to start laffing, but I didn't. I was like you, I sat there bored waiting for them to start their work. I barely felt anything. I tried to go obe. nope. then they said ok, we're done! A long time had passed, but it seemed very short.
