For some reason the intro to this song always bring the same image to me , that of a couple in a space ship having sex without gravity just floating , and a window behind them where you can see the stars and distant planets , then the lirics dont have anything to do with that , but the intro just give me that image each time , such a sexy sound :)
This song somehow puts in perspective why all those religious prophet-type ascetics would wander off into the desert and starve themselves until they had visions. It worked for Jesus!
