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.
The beautiful thing about podcasting is it's just talking. It can be funny, or it can be terrifying. It can be sweet. It can be obnoxious. It almost has no definitive form. In that sense it's one of the best ways to explore an idea, and certainly much less limiting than trying to express the same idea in stand up comedy. For some ideas stand up is best, but it's really, really nice to have podcasts as well.
