There is a word in Buddhist psychology, tathata, that can be translated as „thusness“ or „suchness“. It describes a state in which the totality of our being is present; our awareness is not fragmented or divided. In the state of suchness, some part of ourselves is not sitting elsewhere waiting for something better or different to happen. We are not relating to our experience with either desire or aversion, but rather we accept what comes into out lives and let go of what leaves our lives. We are completely present and not beguiled by the token happiness promised by conventional assumptions. In experiencing the freedom of suchness, we discover who we actually are.
