The ability to change my 'reality' seems obvious, the how maybe not so obvious, idea that the body is the result, the mind is the architect, and spirit is the agent. Mind shapes the perceptions via understanding, where does understanding originate? Right here, right now, I can inject, or withdraw my identity into/out of anything, anytime, disciplne the mind to the degree that you control what you are feeling or thinking at any particular moment, when what you are doing or thinking actually feels divine, then you're on to something!, if it doesn't feel good, then just forgetting it may be the answer, all good things work together to serve the Self, God, Te OM, Shiva, etc,
