"Take no thought for tomorrow," Jesus taught. Yet we are incessantly planning!
Tomorrow has no Being. Being is now. Therefor, the future has no power over one who is awake.
Most of the time we can rest in Presence. And even when planning for tomorrow, we are in the present moment, for tomorrow does not exist.
Our plan will be effective, not to the extent that we worry about the future, but to the extent that we are present in this moment.
