What an interesting metaphor for meditation we have in the tripod. Something akin to the statement attributed to Newton, “If I have seen further it is by standing on the shoulders of Giants.” The tripod lets us see more clearly by establishing a stillness, reducing the distractions of jitter and shake. It allows a smaller aperture so that objects both near and distance are in focus. The capability of a solid grounding allows for enhanced clarity in viewing all things.
Maybe I can add to the list of parallels if I ponder this a little longer. But why is the monthly Buddhist magazine called Tricycle instead of Tripod?
