Living in the moment. We hear a lot about doing it, but how is it done? What does it mean?
The past is a fabrication, a woven together group of memories, created by our present idea of who we are as individuals. Our memory of events, that we take as the past, are recalled from the current moment, are subjective and incomplete. Not only have we selectively constructed our memory, based on whatever we choose to focus on, but the "person" that was in the moment remembered is not the same as the one who remembers.
The whole process is fraudulent. A different version of "you" remembers a past "you" and constructs a memory made of only parts of the original, infinitely vast, moments.
In the same way, we also imagine a future based on our current idea of ourselves, influenced by our fabricated memories of the past. This future cannot become reality because as the idea of ourselves 'moves forward' toward the future we imagined, the individual that imagined it no longer exists. We will have changed before the future ever makes it to us. The present "you" is left always chasing a future that doesn't exist, while realizing "you" have disappeared into the next moment also. It's like a waterfall trying to grab hold of itself!
So, that leaves the present moment. But, there's a catch. We cannot live in the moment either. No one in history has ever lived in the moment- no one. We all live only in our memory of the past, and our imagination of the future(which is really also just a part of the past- headache yet?).
The reason we cannot live in the moment, the infinite present, is because we cannot experience what we are. You can only BE what you are. "You" don't live in the moment, you ARE the moment. Your "I", the witness, creates a past and future that robs you of the being-ness you really are.
To live in the moment, we need only to stop trying to experience and be still. Just BE.
