You don't need to realise you are awareness - if anything, you need to simply understand it.
You are ultimately not the thoughts, emotion or body - you are that which is aware of it.
You are beyond all experience, being the experiencer.
Ultimately, you are not the experiencer either, as there is no experience without an experiencer.
You are awareness, experiencing whatever is popping up for you.
You are THAT.
You don't need to understand anything. You are already awareness and so are totally free, just as you are. Just relax and enjoy.
This is a good book - let me know if you're read it.
