Astral travelling is the kind of experience that can profoundly change one's perspective of life. It certainly did change mine: a little over ten years ago, when I began to experience a series of spontaneous out of body experiences and lucid dreams, my outlook on life and my place in the universe was redefined.
It is one thing, of course, to imagine what it would be like to go through walls as an un-material entity and another to be actually experiencing it. Going through walls is only the beginning though. People undergoing out of body experiences report a wide variety of occurrences that range from meeting other beings not manifest in usual physical reality to having 'astral sex' while in that state.
This series of experiences ten years ago seemingly happened without my conscious involvement but now that I am wanting to induce astral travelling consciously and at will I'm finding the process to be a more difficult one than I would have thought.
Adepts of astral projection can literally train and practice for years before getting to the point of enjoying significant conscious control over the bringing about of such experiences - let alone having command over the out of body adventures themselves.
Thankfully, it is possible to get a big helping hand in the conscious exploration of astral travel by the way of binaural beats (also known as brainwave entrainment).
Binaural beats are sound frequencies designed to influence the brain waves of the listener in a variety of fashions. An astral projection binaural beats recording gets the brain to generate frequencies between 4 and 7 Hz (theta waves) - the same frequencies that the brain would be producing during any out of body experience.
By gently having the brain enter theta mode using binaural beats, it then becomes possible to exit the physical body much more easily.
This may seem a little strange at first but it is a safe tool: binaural beats have been discovered over 170 years ago and have been extensively researched and used since the 1970s.
Best of all, they work remarkably well! They literally can make the difference between success and failure in your exploration of binaural beats as it did for me. Using them still requires you to relax deeply and possibly use an exit technique or visualization to get out of the body but this process is dramatically facilitated by the binaural sounds.
