This word is VERY useful and I use it often. You can be ignorant of something, then be aware of it, then use it enough until you 'get' it to the point where it becomes an unthinking part of your existance... at which point it is "grok'd"... I Grok drumming, but I still struggle a little with the bass guitar. Drumming is second nature to me, but my mind's thinking still gets in the way when I jam on a bass... I haven't acheive a 'Tao-flow' (or Grokking) of it yet.
