Throughout the day, all sorts of thoughts appear, all sorts of sensations, feelings, sounds arise and fall in the vast ocean of consciousness that you are. Everything that appears in what you are, we could call a wave of experience.
And so, this thought is a wave. This sensation is a wave. This sound is a wave. This feeling is a wave. These thought waves, sound waves, feeling waves, sensation waves are all the ocean of consciousness waving, dancing.
