Make sure to rest upon a soft area. You can do this sitting up or laying down. you need to start by making sure you are freezing every part of the body. this includes your legs, arms, hands, fingers, face, facial expressions, eyes, and mouth. Do not allow yourself to go to seep, or let yourself get lost in a ton of thoughts. your mind should also be silent. All you need to do is focus on the silence around you. make sure you use a journal to write down your experiences. This is basically going to be a dream book. keep record of astral contacts as well.
This will help in your magical journey of astral control, lucid dreaming, and shapeshifting in the astral pane. This may help strengthen psychic abilities. Once you are able to accomplish this technique, you can be ready to begin sorcery, and chaos magic.
