Yep, that's it. As long as we are operating in "us vs. them" mode, there will be no tranquility or happiness. With the election only a few days away (thank God!), we are being buried in "us vs. them." The closed mindset of "I am right and you are wrong" will never resolve any problems, as we have plainly witnessed over the past few years. As long as we see ourselves as separate from Spirit and each other, rather than as one unified whole, it is impossible for compassion and understanding to flourish.
The concept of lack contributes enormously to the sense of separateness. This is the false notion that there is not enough to go around. Therefore, I've got to grab my share before someone else gets it. How many wars have happened because of this? Yet everywhere we look we see the infinite nature of life in the extraordinary resources of planet Earth and the unbounded creativity of humans. Competition does not create compassion and understanding. Knowing there is enough for everyone is what creates them. Fear of lack creates the "us vs. them" mode discussed above--and there you have it, an ugly vicious circle.
Let's amp up our practice of simply listening--a good start toward understanding.
