The greater part of human pain is unnecessary. It is self-created as long as the unobserved mind runs your life.

The pain that you create now is always some form of non-acceptance, some form of unconscious resistance to what is. On the level of thought, the resistance is some form of judgment. On the emotional level, it is some form of negativity. The intensity of the pain depends on the degree of resistance to the present moment, and this in turn depends on how strongly you are identified with your mind. The mind always seeks to deny the Now and to escape from it. In other words, the more you are identified with your mind, the more you suffer. Or you may put it like this: the more you are able to honor and accept the Now, the more you are free of pain, of suffering – and free of the egoic mind…

In a fully functional organism, an emotion has a very short life span. It is like a momentary ripple or wave on the surface of your Being. When you are not in your body, however, an emotion can survive inside you for days or weeks, or join with other emotions of a similar frequency that have merged and become the pain-body, a parasite that can live inside you for years, feeds on your energy, lead to physical illness, and make your life miserable. 

So place your attention on feeling the emotion, and check whether your mind is holding on to a grievance pattern such as blame, self-pity, or resentment that is feeding the emotion. If that is the case, it means that you haven’t forgiven. Non-forgiveness is often toward another person or yourself, but it may just as well be toward any situation or condition – past, present, or future – that your mind refuses to accept. Yes, there can be non-forgiveness even with regard to the future. This is the mind’s refusal to accept uncertainty, to accept that the future is ultimately beyond its control. Forgiveness is to relinquish your grievance and so to let go of grief. It happens naturally once you realize that your grievance serves no purpose except to strengthen a false sense of self. Forgiveness is to offer no resistance to life – to allow life to live through you. The alternatives are pain and suffering, a greatly restricted flow of life energy, and in many cases physical disease.

The pain-body has an extremely powerful energetic charge that can easily pull you into unconscious identification with it. You are then actively possessed by an energy field that occupies your inner space and pretends to be you – but, of course, is not you at all. It speaks through you, acts through you, thinks through you. It will create negative situations in your life so that it can feed on the energy. It wants more pain, in whatever form. It is pure pain, past pain – and it is not you. 

The first thing to remember is this: As long as you make an identity for yourself out of the pain, you cannot become free of it. As long as part of your sense of self is invested in your emotional pain, you will unconsciously resist or sabotage every attempt that you make to heal that pain. Why? Quite simply because you want to keep yourself intact, and the pain has become an essential part of you. This is an unconscious process, and the only way to overcome it is to make it conscious. 

To suddenly see that you are or have been attached to your pain can be quite a shocking realization. The moment you realize this, you have broken the attachment. The pain-body is an energy field, almost like an entity, that has become temporarily lodged in your inner space. It is life energy that has become trapped, energy that is no longer flowing. Of course, the pain-body is there because of certain things that happened in the past. It is the living past in you, and if you identify with it, you identify with the past. A victim identity is the belief that the past is more powerful than the present, which is the opposite of the truth. It is the belief that other people and what they did to you are responsible for who you are now, for your emotional pain or your inability to be your true self. The truth is that the only power there is is contained within this moment: It is the power of your presence. Once you know that, you also realize that you are responsible for your inner space now – nobody else is – and that the past cannot prevail against the power of the Now.
