We're talking about the courage that arises in the face of opposition. The courage that's emergent, when one needs to not just stand one's ground, in the physical sense of defending one's land, even though that in many times required courage, as well. But more in the sense of standing your ground inside yourself in a sense of what is important for you, and the values you will choose to act in and fight for?
And we're also talking about courage in the sense of being prepared to step into the unknown, simply by, for example, following a passion or a conviction, or even a line of thought, or a line of discovery. Let that lead you, rather than thinking that you need to know in advance what the outcome will be.
You’re grounding this inquiry of chivalry in the clarity that this is not about fame; this is not about glory; this is not about personal achievement. The core essence is in this idea of being in service to a purpose, or something you believe in.
