Brush: A space inhabited by energy that lets you pass only slowly and which closes again behind you; it is named after the sound of this action, which is powered by your own pushing through. You can only move slowly in this space. This energy that attempts to hold you tight is a reflection of your desire to stand there, unmoving, to protect your face. You lower your head and push on through bush, as it brushes past you. This energy is opposed to rush.
