Essentially Satori is a sudden experience, and it is often described as a "turning over" of the mind, just as a pair of scales will suddenly turn over when a sufficient amount of material has been poured into one pan to overbalance the weight in the other. Hence it is an experience which generally occurs after a long and concentrated effort to discover the meaning of Zen.
