You are not aware of creating your own feelings - including desire and aversion - and so you think of your feelings as authentic expressions of yourself, of 'who you are', as if in some hidden realm you preceded the feelings, as if they offered a proof of your existence. The opposite is likely the case, that you are a construct put forth in order to explain the feelings to your thinking which by itself cannot offer any proof that you exist. Your feeling world changes, often dramatically but slowly, and with certain continuities and buttresses. Even detachment from feeling is taken to be only a new kind of feeling.
