Then what is the way?

I don't think there's a simple answer to that. In any case, to calm down is always the first step. Tolle himself only helps with clues and you can't keep hanged to his lips all your life, though he may be a good teacher to listen at first... even a "master" can't infuse the good will.

... Should I quote Yoda again ?

Oh, another grand wise said: "know that you already know", and that's a bit what Yoda said to Luke.

Edit:

I still feel that negative mental intake can be, and probably most of the time is, quite detrimental to emotional peace.

I know it's gonna look stupid but, why don't you try to feel something else ? ;)
