Who? What? When? Where? Why?

Eckhart Tolle writes in A New Earth:

"I usually congratulate people when they tell me, 'I don't know who I am anymore.' They look perplexed and ask, 'Are you saying it is a good thing to be confused?' I ask them to investigate. What does it mean to be confused? 'I don't know' is not confusion. Confusion is 'I don't know, but I should know' or 'I don't know, but I need to know.' Is it possible to let go of the belief that you should or need to know who you are? In other words, can you cease looking to conceptual definitions to give you a sense of self? Can you cease looking to thought for an identity? When you let go of the belief that you should or need to know who you are, what happens to confusion? Suddenly it is gone. When you full accept that you don't know, you actually enter a state of peace and clarity that is closer to who you truly are than thought could ever be. Defining yourself through thought is limiting yourself." (90)

I'm not there; I'm confused.
