I can watch the swelling and undulating ocean for hours, in a pleasant trance from its gentle constant motions of rising and falling. I love to watch seaweed as it is carried in and out on the tide, undulating in long strands that flow repeatedly back and forth. The bodies of fish undulate as they swim in and out of sight, diving and surfacing with the tide. Even the sound of the swinging of the waves as they crash and ebb undulates pleasantly on my awareness, causing me to relax deeply.
