I have recently experienced a prayer labrynth, which is an experience that uses all the senses to guide a disciple through a prayer journey. I did it at camp this past year and was overwhelmed with a cool sense of God's presence.
Anyway, I was wandering around on www.rejesus.com, and found an online prayer labrynth. It's a really good way to get centered and to listen to what God has to say to us. It's put on by Youth For Christ in the UK. Check it out here. http://www.yfc.co.uk/labyrinth/labyrinthswf/map.html
