“Why do we resist our energy? Why do we resist the life force that flows through us? The first noble truth says that if you are alive, if you have a heart, if you can love, if you can be compassionate, if you can realize the life energy that makes everything change and move and grow and die, then you won't have any resentment or resistance. The first noble truth says simply that it's part of being human to feel discomfort. We don't even have to call it suffering anymore, we don't even have to call it discomfort. It's simply coming to know the fieriness of fire, the wildness of wind, the turbulence of water, the upheaval of earth, as well as the warmth of fire, the coolness and smoothness of water, the gentleness of the breezes, and the goodness, solidness, and dependability of the earth. Nothing in its essence is one way or the other. The four elements take on different qualities; they're like magicians. Sometimes they manifest in one form and sometimes in another. If we feel that that's a problem, we resist it. The first noble truth recognizes that we also change like the weather, we ebb and flow like the tides, we wax and wane like the moon. We do that, and there's no reason to resist it. If we resist it, the reality and vitality of life become misery, a hell.
The second noble truth says that this resistance is the fundamental operating mechanism of what we call ego, that resisting life causes suffering. Traditionally it's said the the cause of suffering is clinging to our narrow view. Another way to say the same thing is that resisting our complete unity with all of life, resisting the fact that we change and flow like the weather, that we have the same energy as all living things, resisting that is what's called ego.”
