We all live under a certain amount of stress and not all stress is negative. In fact, according to the mosr recent scientific research, nothing is static. Even a rock is in constant movement although it appers to be solid to the human eye. So stress and tension is a part of who we are, at the molecular level.
Being present to one's pain and suffering instead of denying or fighting it, is said to open up the door of transcendance. We often hear this saying : " What you resists, persists". So I truely believe that when we get sick...we should embrace and accept everything, even the pain and possibility of death, to be able to transcend both!
