Elkhart Tolle assumes that you are ‘conscience’ of being the ‘observer’ of your thoughts and you live in the ‘present moment’. You are not your thoughts, you are the observer. Someone is ‘un-conscience’ when they think they ARE their thoughts. They are ‘un-conscience’ of their being the ‘observer’ of their thoughts. They are not living in the ‘present moment’ because they are living ‘in their thoughts’, the ‘story’ they are creating in their mind.
