#unconquerable

Sickness is a hindrance to the body, but not to your will, unless itself wills it.

I must die. But must I die groaning? I must be imprisoned. But must I whine as well?

'Tell the secret.' I refuse, for this is in my power. 'But I will chain you.' What are you saying? You may chain my leg, but not my will; not even Zeus can conquer that.

When a raven croaks in an inauspicious manner, let not the impression carry you away, but immediately distinguish in your mind and say: 'None of these omens is for me; but either for my body, or my property, or my reputation, or my children.'

No man can rob you of your will.

It is the power of the mind to be unconquerable.
