“ *You are not yet in the Emerald Dream. First, you must remove your earthly shell...* the voice in his head instructed. *As you reach the state of sleep, you will slip your body off as you would a coat. Start from your heart and mind, for they are the links that most bind you to the mortal plane. See? This is how it is done...* - Chapter 4 ”
