Nirvana means to extinguish the burning fires of the Three Poisons: greed, anger, and ignorance. This can be accomplished by letting go of dissatisfaction.
Eating with the fullest pleasure - pleasure, that is, that does not depend on ignorance - is perhaps the profoundest enactment of our connection with the world. In this pleasure we experience and celebrate our dependence and our gratitude, for we are living from mystery, from creatures we did not make and powers we cannot comprehend.
Wendell Berry (1934 -)

We are not innocent children victimized by a big bad world; if our world is big and bad, we made it that way. This is what the Buddha taught. The “other” is the child's boogeyman, the projection of our own fears onto a terrifying object of our imagination, which in turn terrorizes us. Our ignorance is not seeing that we are the other. We cannot afford to confuse innocence with this ignorance. Violence is not a permanent, immutable, fixed object. It is a state of mind, an expression of ignorance, with no more solid substance than a cloud. We cannot make a frontal attack on violence. Even protecting ourselves from it fuels its boogeyman existence. But the Buddha taught that we can change. This was his good news: that there is a way to alleviate suffering by freeing our minds from greed, anger, and ignorance. Yet until we apprehend the ways in which we are Oklahoma City, the bombs and the baby bears, the victims and the violators, we will continue to blame “them,” all the while proclaiming our innocence and evading our responsibilities.
"Most people, including ourselves, live in a world of relative ignorance. We are even comfortable with that ignorance, because it is all we know. When we first start facing truth, the process may be frightening, and many people run back to their old lives. But if you continue to seek truth, you will eventually be able to handle it better. In fact, you want more! It's true that many people around you now may think you are weird or even a danger to society, but you don't care. Once you've tasted the truth, you won't ever want to go back to being ignorant"
Socrates (469 - 399 BC)
