From the moment of birth we are perceiving with our senses, we are feeling with our being. We are interpreting what we see and experience. We are responding to the environment in our own unique way. We are constantly learning how to respond and accordingly modify our behavior to get the response that we desire. We do this until our death, but very often along the way, we stop modifying, for some reason we respond every time in the same way, even though we do not get the response we desire. In other words we become fixed in our ways, we respond unconsciously in a habitual way.
