The best teachers have showed me that things have to be done bit by bit. Nothing that means anything happens quickly--we only think it does. The motion of drawing back a bow and sending an arrow straight into a target takes only a split second, but it is a skill many years in the making. So it is with a life, anyone's life.
Mindfulness helps us freeze the frame so that we can become aware of our sensations and experiences as they are, without the distorting coloration of socially conditioned responses or habitual reactions.
