I like sunny days. But ya know, the true worth of this Practice is tasted on the stormy days ... the really hard days ... when life is battering us about and all seems dark. That's when the darkness is seen as also light. Peace, clarity, optimism, acceptance, yielding, "at oneness" ... these are some tastes of this practice which (arising from somewhere within) stand out most clearly at times of turmoil, chaos, resistance, despair and fear.
Somehow, there's stillness amid and as the storm. Somehow, there is peace (not at every second perhaps, not at each moment of the crisis when we are being battered about ... but abiding peace nonetheless, when we least expect it.)
(oh,yes, I know that there are supposed to be no "benefits" sought from this practice ... but that does not mean there are no benefits)
