The thing is, being in the moment is straight forward at times and at other times we get dragged into our thoughts and we become unconscious within the mind.
It is journey and our level of consciousness grows. We have to undo years, often a lifetime, of conditioning that convinces us that we are our mind.
However, once we experience the conscious moment free from the mind and its endless repetitive thought patterns we never will go back to continual unconsciousness. It is the beginning of the end of our association with the mind and ego.
We realise we are no longer our mind, it is just a part of us, the same as our foot is.
