I started to think why do people always use "slow punch" for meditation. Why don't people use "fast kick" for meditation instead?
Since combat is always fast, it makes sense to train your meditation fast too. This way, you can kill 2 birds with 1 stone. /QUOTE]
Maybe because if you can do something slowly you can also do it quickly but the reverse is not true.
By doing something slow one can really concentrate and develop the movements, techniques and concepts. Not as easy when doing something fast
Then again, it all depends on the level you wish to achieve.
