Let go of your fear, & be.
You can "be" all sorts of things...you can be careful, be reckless, be generous, be shrewd, be unkind, be welcoming, be together, be alone...and you can be all these various things to no end. But at the very least, and perhaps even the most, you must simply BE.
No external circumstances can affect this, perhaps even death. Nothing can truly take your "be"ing. So relish each moment, let go of your fear and BE.
Additional food for thought, for all you Judeo-Christian sympathizers out there. The Judeo-Christain God's name is Yahweh - I AM. The greatest "be"ing simply is, and that is apparently enough said about His name, his essence & existence. We are purportedly made in His image.
