For best sound quality, I recommend using headphones or ear buds.

Lie down on your back either on the floor or your bed.  You may like support under your knees and a thin pillow under your head.  Your body temperature will drop, so either cover yourself or have a blanket nearby.  The idea is to remain still during Guided Rest, but do not become distracted by discomfort--adjust yourself or roll onto your side.  You can also do this meditation sitting up.  Please do not listen to it while driving.  Enjoy!
