We keep track of time by our clocks and calendars. We schedule our days, weeks and months by them. Sometimes, there doesn’t seem to be enough time. Other times, there seems to be more time than we need.
Each life spends a certain amount of time on this earth. The amount is unknown, but is counting down each and every second of the day. Time is constant, neither slowing down or speeding up. What is done with that time is up to each life.
