How To Astral Project

It isn't a matter of believing in it or not.

It doesn't exist.

And if you really believe that it does, you need to seek medical help immediately.

I'm serious. Meditation is fine, but Astral Projection? Come now.

The blood moving through your arteries. Seriously - you are so relaxed and focused that you hear your own blood move.

It's the sound you hear when you're concentrating. It's a pitch set off by the frequencies in your head.

By not allowing people to answer, you're shutting yourself off to answers. Are you afraid you're wrong about your beliefs? Refusing to acknowledge opposition is a sign of that.

Some experiences like this are possibe during meditation.

Actually its the sound of your physical brain(no joke).

i've had a few OOBE's, but i don't recall any such sound. may be some kind of vibrational wave interference, a slight difference in 2 frequencies that results in an audial pulse.

astral vibrations or astral noise.

Your head is a bees nest..

It is your ears either ringing or your blood flowing through your ears. You can hear similar noises sometimes when you are lying in bed near to sleep.

Each plane has a different sound. I don't remember what they all are, there's bells, the sound of the ocean, singing, bees buzzing, etc. Eckankar has a listing of the various sounds and colors on each plane.
Mguel- shared dreams are rare, my wife and I are very close spiritually/vibrationally and we've only had a few.

Even though astral projection is more of a process of psychic energy transfer than an actual physical state, it still affects the physical body during projections. One can never escape the mind-body connection. For every change in psychic energy there is a corresponding change in body reaction.

The basic cause of your experience of a roaring sound is a change of blood flow. I have no idea the exact reason for the blood flow change, but that change affects all of the head and ultimately the ears. So, it's the change in blood flow around the head and ears during a projection that causes the experience of either a rushing sound, or even a sudden sensation of not being able to hear much of anything. Very weird.

That's the cooling fan of the astral projector.

Why do you resist answers that might oppose your thinking?

I spent from my early teen years, until my mid adulthood convinced I was having astral projection experiences. One early incident was so compelling it changed nearly my life. I read the famous book on the subject by Robert Monroe and even spoke with him once. I heard, and still DO hear the humming sound. No one could tell me it wasn't happening.

But the more I read, the more I learned, the more I came to know the truth, what we see as Astral Projection is a symptom of Hypnagogia.

http://en.wikipedia.org/wiki/Hypnagogia

In the state between wakefulness and sleep, dream-like states intermingle with sleep and deliver sensations like nothing we perceive at other times. This is when lucid dreams (also associated with Astral Projection) and sleep paralysis occur. I've heard an explanation for the hum before– I believe it is a fast vibration of one of the muscles in the inner ear that happens during sleep paralysis. It should also be noted that some people attempt to interpret images in this state with cultural references– incubuses, alien abduction, ghosts, extra. The more you read, the more you'll see all these things tie into Hypnagogia.

Still, there's plenty we don't know. I don't dismiss the possibility of out of body experiences. I'm simply saying it's FAR more likely that these experiences are due to a transitional sleep state.

I've practiced deep meditation before, and I think the vibrations we experience are a sort of "white noise" produced by the brain when all external stimuli are cut off. It's much like the high-pitched tinnitus you hear if you completely cover your ears and concentrate. The neurons themselves will produce signals even if there is no external sensory input.

Yes. I have. I couldn't say for sure, what you're hearing, is such as that which I've heard, but if it is, you should seek an enlightened Guru to initiate you: I presume that you are a yogin, and are practicing yoga; if not, you should explore this wonderful, ancient science.

The kind of sound that I'm referring to, in yoga, is termed "anahata nada"(or nadam): these are Sanskrit words(am unable to type in their diacritical markings) = "sound without instrument".

The sound is coming from the mind; has nothing to do with ones physical hearing apparatus.

One of my two former Gurus, was a Hindu(a Brahman)by the name of Dr. Rammurti S. Mishra, M.D.: held multiple medical degrees(nero-surgeon, endocrinologist, psychiatrist - he collected degrees)and a Sanskrit scholar.

He authored three books on the subject of meta-physics. The first, "Fundamentals of Yoga" was on a best seller list for years, back in the 50-60's or there abouts. He died in 1993, but I think there is still an article about him on the Internet: just type in his name as above.

If you can check out "Fundamentals of Yoga" from the library, or possibly order it from Amazon.com, chapter #-28 entitled "Anahata Nadam-OM-Sphotam" is most informative about "transcendental" sound.

Good luck,
