Put it this way: the past is already written.
The future is an infinite space of potential.
To move forward embrace the unknown!
If you spend most of your energy trying to recall the past, that's where you keep your consciousness.
It does give you some security and a sense of stablity but limits you as well.
It is like trying to walk forward while looking backwards.
"What can I do to be slightly ahead to where I am right now?"
To your Yoga!
