I must accept "it" is unknowable.
This means I may either fight against this truth (that "it" is unknowable) or surrender to it. In surrendering I allow myself to be consumed by "it" (if that be what "it" wants to do, if "it" can so do). But also, I can embrace it (the truth) and thus, embrace "it."
What word could best point to "it?" Uncertainty comes first to mind.
There it is. The method, the process, the... solution?
Embrace uncertainty, again, Merlyn, our friend.
Keep wonderment alive!
And thus the lesson for the day reads - That which fuels life is the ever unfolding uncertainty of it. When the fuel runs out, life ends.
May the fuel never run out.
So be it.
