Learn How To Get Out And Come Back To Your Body Consciously
Astral projection and lucid dreaming happen during the theta state of the brain or REM sleep, meaning at the time of your sleep when you have dreams. All human beings dream. Even those who can't remember their dream in the morning.
Because you dream, you subconsciously astral project at night.
You may not be aware that sometimes at night, you(as the consciousness) leave your physical body and travel the invisible worlds to visit friends and places, and get back to your physical body when it's time to wake up.
You will wonder “If I do astral project unconsciously in my sleep, why don’t I remember a thing in the morning?” That’s simply because whatever you do unconsciously can’t be remembered. Learn to become conscious during your sleep, and you should be able to remember your astral projection experiences.
The most important benefit to note is that astral projection gives you the chance to help more people in a much more effective way from the astral world than you can from the physical would.
For example you can learn to cure many people from the astral world, or if you are a teacher, you may help many more students to understand better. You can go fly or teleport to distant galaxies and higher dimensions to learn almost about any subject. This is all possible while keeping altruist intentions.
