What we call opposites like light and darkness, are different expressions of one whole. I think the Buddha's teaching is not that light and darkness depend on each other for their existence, but that our awareness of light and darkness depends on their existence and their contrast. I think what Thich Nhat Hanh is saying, and I hope he is saying, is it is for us to choose and perform right action, both inwardly and outwardly, because it is right, and not to oppose anything, not to impose our view, not to try to change the other, and not to accomplish any goal or agenda. Views that are different than mine can expand my view and contribute to collective awakening. There have been times that I have felt anger at what I saw as injustice, and my willingness to be open helped me see positive and truth in what the other was doing which transformed my anger into compassion. What helps me fous on my conscious choices is my knowing that the only thing I can control is my conscious choices, and knowing that my judgmentalness and trying to control outcome get in the way of my right conscious choices.
