1.Consciously Control Your Dream
Take full advantage of the moment in the morning when you are first waking up. When you realize you are waking, before opening your eyes and allowing your consciousness to fully return to your physical body, stay in limbo.Do this as often as you can and this will train the brain in preparation for splitting your consciousness into an out-of-body experience or astral projection.
2. Set Your Focus
When we imagine different scenarios in our minds, whether it is a worry or a fantasy, we transmit a brain wave frequency. Dependingupon the potency of the thought and by whether it is positive or negative it will create a ripple effect that can be viewed like a pulse or a sound wave, that is completely in line with the beat of your heart and transmits from your mind’s eye.
3. Start The Wave
There are many techniques in order to loose the spirit from the body or split consciousness in order for free travel. It is not well-practiced to immediately hit the astral realm, as psychosis can easily follow if not prepared for the journey. Taoists often warn about the dangers of extended and frequent astral travel and I can attest to this as well.
Lie down in a comfortable position, in loose fitted, light clothing. Set your focus at the bottom of your feet and visualize raising your energy from the bottom of your feet to the top of your head. Feel it every step of the way.
When the energy reaches the heart, let go of this plane and everything in it, this will be a test of non-attachment and it will make the difference between reaching astral travel or not.
Finally, take a nice deep breath and bring the energy into the throat chakra. Let go, allowing the energy wave to wash over you completely.
