Yes, it is totally meaningless. The reason why...DO you want to really know WHY? And are you going to listen?
The reason why is because YOU are THEM and THEY are YOU. So when you hurt someone else you are really hurting yourself. You think you are separate but you aren't. There is no such thing as separation. There is only the IDEA that we are separate. Separation is an IDEA, not a fact. You will understand what I mean, when you consider that everything in the universe is intrincically tied together into one UNITY. The UNITY of "THE" ONE. There could only be separation IF there was something ELSE. But since there is only the UNITY, there is nothing ELSE. The else is an illusion. It, like separation, is an idea.
Understand, there is a difference between an IDEA and Absolute Reality. Absolute reality is what the UNITY is BEING. An idea is a subjective perception of the Unity as separate.
This is EXACTLY and PERFECTLY what the Golden Rule means:
Do UNTO others what you would have them do UNTO you.
The reason is clear - the reason is perfect - the reason is consistent. You are them and they are you and there is only ONE.
Therefore, revenge upon another is revenge, an act of violence, against the SELF. When you hurt another, you hurt yourself.
Now, I will tell you how it works...you hurt another...and that hurt goes out into the universe, into the unity, and it comes back to you, maybe six months later or a year later or two years...however long it takes, it comes back, and you are hurt by ANOTHER just as you hurt that person in the past. The one who is hurting you is YOU in THEM...it is what you did coming back to you in full force.
The reality is - you are looking into a mirror of yourself, everywhere you look is YOU...in a different body, in a different place, so it seems and so it appears like there is separation when there is no separation...it is an illusion, the false concept of separation which you are confronted with.
