Feeling no pain sounds like it would be amazing. Pain, however, is a communicator and when we find every means possible to avoid feeling that pain, we are figuratively gouging our eyes out. When we ignore, mask or hide pain we are choosing to ignore what our body and mind is attempting to communicate with us. By avoiding addressing pain, we cannot identify and fix the root cause of the pain.
Emotions are powerful. While they sometimes seem beyond our control, as we begin to gain a greater awareness of our emotions, the events that lead to them, the thought process that is involved with them and the way they are elicited, we can begin to make changes to our environment and the way we think which will help us alter the automatic response that is associated with our emotional experience. While many emotional responses are a learned response from past experiences, we can change our learned response to be more inline with what we would like our emotions to be.
