The fist group of meditations require you to learn to feel and become aware of your own body.  First step is to learn to feel where your arms, legs etc. are.  Second step learn to feel everything inside you. 

Think of yourself as a glass of water.  Pour water into an empty glass, notice how it fills the bottom first.  Picture yourself filling up with your awareness.  Start with your toes and feel every part of them, flesh, muscle and bone.  Slowly increase the area of your awareness.

Final step is a little harder.  It requires filling yourself up with peace and tranquility.  To do this you need to let go of the world around you and everything in it.  The idea is to create something within yourself where none of it is important.

To accomplish the goal of letting me possess your body requires you to learn some specific meditations.  Some of these will be easier to learn then others.  All so be aware that some of them could take quite a while to learn.

The meditations themselves are based on physics principles.  In fact there are four fundamental forces that don't have any reliance on anything else.  Those are Electromagnetism, Gravitation, Weak Nuclear and Strong Nuclear.

Basic definitions for these are.  Electromagnetism is the change or movement of chemicals with in an object.  Gravitation pulling objects together.  Weak nuclear movement with in the atom.  Strong nuclear movement between atoms.

You could also say there are two different areas.  With in you and outside of you.  There is also movement with in you and with outside of you.
