I'm in love with this Ultimate Nap CD. With 10, 20 and 30 minute tracks I taylor my nap according to how much time I have, and how much I need a nap! These days as soon as the track begins my body/mind is conditioned to immediate relaxation and quite rapid sleep! I often wake after 10 minutes feeling like I've woken up from a good nights sleep! My naps feel more restful and the chiming sounds at the end of the tracks wake me gently and pleasantly. I slowly come to, enjoying the 4 chimes consciously choosing to connect with Body, Mind, Emotion and Spirit, one chime at a time.
