Suffering can be differentiated from pain. There is pain in life, without doubt, but suffering is the extra tension in the mind that is unable to accommodate change and accept the truth of its experience. The first two noble truths are that life is difficult and that suffering is the tension in the mind that insists an experience be different from the way it is. It’s the imperative in the mind that this moment be different that causes our suffering

The essence of the practice life involves cultivating awareness. This process has two basic aspects. The first is clarifying the mental process. The second is experiencing — entering into awareness of the physical reality of the present moment. When we’re standing in the muddy water of everyday life, practice is often not simple and clear. But part of our challenge is to bring a certain precision and impeccability to our efforts. That’s why it’s important to keep returning to these two basic aspects of practice: first, seeing through the mental process, with all its noise; and second, entering the non-conceptual silence of reality as-it-is. As practitioners we learn to honestly and relentlessly observe the mental or conceptual process — thoughts, emotional reactions, strategies and fears — and then bring ourselves back again and again to the physical reality of the present moment.
One of the key, frequent, things in life is having to deal with disappointment. And consequently a lot of our suffering comes from this area, as like this first quote says. We prefer to rerun the memory of an event or a feeling or some words, rather like a dog returning to a bone. A wiser way of acting is suggested in the second quote, staying as close as possible to the felt sense of the experience, thus limiting it spinning off into a reactive cycle of thoughts and emotions. 
Our practice is not to shut everything out; it’s to remain conscious of our environment and what’s happening in it. Then we can deal with it appropriately. We can open the door to our angry thought, listen to it, and then ask it to leave. We recognize it as a thought and don’t mistake it for who we are. That’s the point. It shifts the experience. Instead of thinking, “I’m really angry right now,” we think, “Oh, look, an angry thought has entered my mind.” It’s easy to let go of a thought that’s a guest in your mind; it’s harder when you take on the identity of the guest. 
Emotions are mixes of “felt senses” and activities. Witnessing them is helped by the simple fact that the body resonates with the moods and impulses that run through it. (When we’re angry we tense up and the heartbeat changes; when we’re loving and joyful, the body feels vibrant and so on). This resonance gives us a way of addressing the heart by addressing the bodily aspect, of steadying or relaxing the emotion by grounding attention in the body and simply breathing.
