“Unnecessary judgment”, lets look at what that means. Since Tolle doesn’t say judgment itself is wrong, he says some judgment is unnecessary, so what kind of judgment is that? Judgement determines value, good and bad value. pleasure and pain value. Judgement divides the One into Two, so judgment is a wound the cleaves the ONE. Reality is actually ONE, unless you are schizophrenic and see reality as a split screen. So what does judgment cut into two opposite halves?
If I judge that I exist as a separate thing, then being a separate things is of ultimate value. First I just exist, then—since my existence is the ultimate value–there must be Two, Me and the world. Given that Original Sin of the hatchet, once divided the One is infinitely divided, and every judgment just cuts another pair of this and that. There is no end to this hall of mirrors.
Tolle Teaching invites us to observe the Original Judgment that condemns me to a life of divisions and suffering. The judge and the judged are One.
