Meditation: Sit or Spellbook

[Rasah]

I have a question on how meditate works in P99. I remember on original classic that in order to meditate, you had to have the spellbook open until you reached a certain level. Then once you hit that level, sitting was good enough.

Is that the case here? If so, what is that level you have to hit?

It's been 6 years since I retired from Live, and I can't remember half of this stuff.
