The answer lies in the old Pogo comic strip: "We have met the enemy and he is us."

Suffering seems part of the whole human experience so my guess is that NOBODY fits the above description, regardless of how much they might want to.

Who among us understands all the causes of human suffering? NO ONE UNDERSTANDS ALL.

Who among us understands the choices people make in responce to the suffering they experience? SOME UNDERSTAND CHOICES OF OTHERS--OTHERS DO NOT.
Who among us has compassion enough to understand human suffering, and not judge? ALL THE TIME, NONE--SOME OF THE TIME, SOME DO

Who among us is free of suffering? SUFFERING IS A STRONG WORD. IT IS ALWAYS A THING OF EBB AND FLOW...

Very profound questions while yet even a more profound answer by "maridon"

If the enemy is "us" how do we win....I would say that the enemy is within and without us...but the power of that enemy is in the inability of the indivisual. We give up ground to the "enemy" whoever or whatever he/she maybe

Do we all have the same enemy? No matter the circumstances we find ourselves in?

I understand. And so do each of you. Deep down inside everyone is all the wisdom they could ever need. When it is said we are the enemy that is partly true, partly false. The enemy is not who we really are but a part of us. We have been fooled into thinking that it is us and even the superior part of us. But I tell you that it is not superior to us. Any time you hear a negative voice, from within you or from outside of you, that is how you know the enemy. Any negative thought or feeling is an incorrect or misguided thought or feeling. If the negative voice is from outside you, it is not the person who is the enemy that it comes from, but that same negative part of them that is their enemy as you and every person has inside them. It is the source of ALL human suffering, period. It is not a great mystery and there is no magic. To know this one only has to learn to pay attention. To be totally free from suffering is possible for all beings. Pain need not turn into suffering at all. Each and every-time you suffer, the lessons you need to be free from suffering is inside the suffering itself. Yet everyone spends all their energy trying to avoid the suffering. Fight the suffering and you fight the lesson. All you have to do is really look and you will see and know this to be true.

For more information look up the following names, just a small sample, because their is the truth inside everything and everybody, but sometimes you need a finger to point the way:
Eckhart Tolle, Guy Finley, Alan Watts, Gil Fronsdal, Depak Chopra, Roy Masaters, Thich Nhat Hanh, Just to name a few. Read. Be patient. Do not judge. These writers only open up the truth inside of you. And it definitely is inside of you. Good luck, much love!

We are the answer to all your questions here. And we have the power to change. It lies within us. We need to find that power and use it for good.

who of us without it could understand love?

Those among us who understand the causes and choices in relation to human suffering and those who have compassion, understanding and are without judgement are those of us who suffer or have suffered.

Who among us is free of suffering? Those that don't understand, those that don't have compassion and those that judge.
