“Many animals experience pain, anxiety and suffering, physically and psychologically, when they are held in captivity or subjected to starvation, social isolation, physical restraint, or painful situations from which they cannot escape. Even if it is not the same experience of pain, anxiety, or suffering undergone by humans- or even other animals, including members of the same species- an individual's pain, suffering, and anxiety matter.”

“Anxiety and anticipation, I was to learn, are the essential ingredients in suffering from pain, as opposed to feeling pain pure and simple.”

“Our possibilities of happiness are already restricted by our constitution. Unhappiness is much less difficult to experience. We are threatened with suffering from three directions: from our own body, which is doomed to decay and dissolution and which cannot even do without pain and anxiety as warning signals; from the external world, which may rage against us with overwhelming and merciless forces of destruction; and finally from our relations to other men. The suffering which comes from this last source is perhaps more painful to us than any other.”

“Pain is not the same as suffering. Left to itself, the body discharges pain spontaneously, letting go of it the moment that the underlying cause is healed. Suffering is pain that we hold on to. It comes from the mind’s mysterious instinct to believe that pain is good, or that it cannot be escaped, or that the person deserves it.”

“Pain is a relatively objective, physical phenomenon; suffering is our psychological resistance to what happens. Events may create physical pain, but they do not in themselves create suffering. Resistance creates suffering. Stress happens when your mind resists what is... The only problem in your life is your mind's resistance to life as it unfolds. ”

“Pain is inevitable; lives come with pain. Suffering is not inevitable. If suffering is what happens when we struggle with our experience because of our inability to accept it, then suffering is an optional extra [p. 19].”
