it seems to me that all you are saying is that meditation (misspelled as "mediation" throughout) can serve certain useful purposes.

Along with religion, praying, and making stuff up. Meditating (thanks for the correction) was just an example.

BTW, slowing a drum rhythm down for a beginner to hear how it goes is more difficult than playing it to speed.

Oh, I also don't get the spade comment either. I mean I agree a spade has useful purposes but what is the point of saying so here?

Not exactly sure what you are trying to express here. Do you mind further explanation?
