is being capable of understanding the views of others and working together with them.
I learnt this from my Kabbalah meditation.
How often we stick to what we think, maybe even know for sure, is right, and hang on to it totally not seeing how the other person's face is changing, not reading the body language that says 'please, just let it be..okay you're right....why do you want to pummel me', not feeling, maybe blocking out, the sensitiveness of the moment for the other person.
Besides estranging the person you are trying to prove is wrong, you lose a friend, you become that much more hard-hearted, not realizing that chances are that one day you may just find yourself in the same situation.
It would be better, instead, don't you think, to work around the point of dissension, to understand what the other person is trying to say, try to get what is hidden inside, and then work as equals?...with respect?
