Actually, everything here is done because of others; they never sacrifice for themselves. They do not die for themselves; they do not die for themselves.
They want a lot, but they must obtain it themselves. If life truly cannot be gained because of oneself and one must plunge into fire and water without hesitation, what can they do then? What can they think, say, or do?
What can they sacrifice for themselves? Who knows? Who knows what they can do, what they can say, what they can sacrifice for? Because they know that everything they do now is for others and they never treat themselves poorly.
I've said that life never distinguishes between right and wrong. If life never has justice and value, if life never has all of this, what could they possibly say or do then? There are so many wrong things to do in life, so many right things to do; who could truly know what is right and wrong?
