You can’t think and be aware at the same time

Did you know...
...that you cannot think and be aware at the same time? Thinking is always of the past or the future; awareness is being right here, now. Verify this for yourself. For five minutes, try remembering the incoming and the outgoing breath. Let your attention be with the breath. You may start by being aware as the breath is coming in, but no sooner has it turned out than you are somewhere else. Suddenly you remember that another breath is coming in. The first breath has already gone out, but you were not there to see it. A single thought and you became unaware.
