" The balanced state of body and mind that occurs through zazen practice can also occur spontaneously in other situations. As a musician I used to find it when playing onstage. All consciousness of myself and the outside world would vanish, to be replaced by a fluid state of action alone, in which thought and feeling ceased to be important and in which sense of self and other utterly dissolved. Athletes often experience moments like this. So do artists of various kinds. So do many people involved in a whole range of activities to which they have fully devoted themselves. And so, quite often, do lovers engaged in sex. "
