Greetings Jason,
The opposite is likely to be true. As we get older, our Astra-Mental body becomes progressively "looser", and therefore easier to project.
Robert Monroe, I think Muldoon and many other famous projectors are testimony to this. Monroe was projecting regularly right up to the time of his passing from the physical world.
It seems to me that your were fortunate in your earlier experiences which sounded as if they were spontaneous. It might well be that you need to practice a specific method now like most other people. Energy will fluctuate constantly, but can still be accumulated.
Don't be despondent - just find a method and keep practicing.
With best regards,
Adrian.
I have been experimenting with astral projection for 12 years now, and I find that as every year passes,my abilitys and experiences seem to become less and less.when I first discovered astal projection when I was 15,I would have intense and violent vibrations almost nightly, many times actually separating from the physical.as the years went by,the vibrations increased in frequency (speed) and became much less violent (which is good[:O]).although I've had many incredible,unforgettable experiences in astral projection, I've noticed that thew experiences become less and less frequent.now i'm lucky if I have a really good one once or twice a year!what the hell is going on?[:(!]have I used up some "inner reserve" of energy? what can I do to change this?
