This is the rule, and there is no way to free oneself of it: as soon as the thought has arisen, it must be followed to the very end.
“I even I, am he who knoweth the roads
Through the sky, and the wind thereof is my body.
I have beheld the Lady of Life,
I, even I, who fly with the swallows.
Green and gray is her raiment,
Trailing along the wind.
I, even I, am he who knoweth the roads
Through the sky, and the wind thereof is my body.”
Ezra Pound | “De Aegypto”
