"I do not see how one can surrender to suffering."

Forget about surrender for a moment. When your pain is deep, all talk of surrender will probably seem futile and meaningless anyway. When your pain is deep, you will likely have a strong urge to escape from it rather than surrender to it. You don't want to feel what you feel. What could be more normal? But there is no escape, no way out. When there is no way out, there is still always a way through.

So don't turn away from pain. Face it. Feel it fully. Feel it -- don't think about it! Express it if necessary, but don't create a script in your mind around it. Give all your attention to the feeling, not to the person, event or situation that seems to have caused it. Don't let the mind use the pain to create a victim identity for yourself out of it. Feeling sorry for yourself and telling others your story will keep you stuck in suffering. Since it is impossible to get away from the feeling, the only possibility of change is to move into it; otherwise, nothing will shift. So give your complete attention to what you feel, and refrain from mentally labeling it. As you go into the feeling, be intensely alert.

At first, it may seem like a dark and terrifying place, and when the urge to turn away from it comes, observe it but don't act on it. Keep putting your attention on the pain, keep feeling the grief, the fear, the dread, the loneliness, whatever it is. Stay alert, stay present -- present with your whole Being, with every cell of your body. As you do so, you are bringing a light into this darkness. This is the flame of your consciousness.
