Calcite is a powerful mineral that increases and amplifies energy. One specific way calcite is used, is to amplify your ability to astral travel. Astral projection (or astral travel) is an interpretation of an out-of-body experience that assumes the existence of an "astral body" separate from the physical body and capable of travelling outside it. Astral projection or travel denotes the astral body leaving the physical body to travel in an astral plane.
Before we get into techniques, you should know that there are hundreds if not thousands of different techniques to get your soul out of body. We are all unique. One technique that works for some people, may not work for others. I recommend you try one for little while, and move on to a different one if you don’t succeed.
The Rope Technique: This technique has been formulated by Robert Bruce and is one of the most effective techniques around. A key ingredient to this projection technique is an invisible, imaginary ROPE hanging from your ceiling. This ROPE will be used to exert dynamic pressure at a single point on your astral body to force its separation from the physical.
Another way you can achieve astral travel is to watch yourself going to sleep: Lie down comfortably on your back, facing the ceiling. Relax your body and clear your mind of unwanted thoughts. Relax even more. Tell yourself that you are going to watch yourself in the act of going to sleep. You must be very clear about your intent. You’re going to let your body sleep while your mind will remain alert throughout the entire process. Tell yourself you will retain consciousness even while your body is going to be in complete “trance”.
