只有我们内心坚定希望，才是我们保持不断努力，不断争斗，不断勇往直前的力量来源。

Only when we have a strong hope in our hearts, is our constant struggle, constant struggle, and a source of strength to keep going.

我不会停止内心的争斗，我的剑也不会在手中睡大觉。

I will not cease from mental fight, nor shall my sword sleep in my hand.

youdao

内心的折磨使他们像受到伤害或威胁的野兽，要么选择争斗，要么选择逃逸。

And they react to these inner feelings just as any animal reacts to any hurt or threat: by readiness to fight or to flee.
