“Speaking words of wisdom…”

"Take care" is unoptimistic, assuming a dreary miersable world which requires its occupants to focus lest they never see each other again, their planes not arriving properly unless they doublecheck the destination with a flight attendant. The care is wariness, not meticulousness. And yet, this also assumes a world in which occupants are in complete control over their outcomes: with enough care, anything is achievable.

Whereas "[god] be [with you, [wherever you may go]]": that has a freedom, and the opposite of determination. "[see you] later": clingy, certainly, but acknowledging a bond, by which some day the interaction will be resumed. Unlike "take care", which enjoins us with our own responsibility, these conclusions are passive, with a defined or undefined higher power in control of what will happen.

For I like being, not the overachievement of being. I do not listen to make; I hear be. Lack of control does not bother me; for there is a difference between external and internal control, and what I do not is being unable to control internals, and having to control externals. "Take care" is not my world.

“…Let it be…”
