This blind confidence, when the mind says - you know about something, that is the biggest obstacle to realisation. Truth is - nothing can be known. And whatever you know is a hallucination of the mind. You realise this when you are utterly quiet, in silence the truth of consciousness reveals itself. The moment you realise that - you don't really know and nothing true can be known by the mind, you are free. That is, awakening is not an object of knowledge happening in the mind. It's your natural state ever-present. This is transcendence of the mind.
