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." When you fully 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.
Eckhart Tolle, A New Earth: Awakening to Your Life's Purpose
clarity, confusion, peace, thought
