If you expect your life to be full of ups and downs, then your mind will be much more peaceful.
Thubten YesheOur normal tendency is to feel dissatisfied and to criticize our body, speech, and mind - My body is out of shape; my voice is unpleasant; my mind is confused. - We are so caught up in this pointless, neurotic habit of criticism that we disparage others as well as ourselves. This is extremely damaging.
Thubten Yeshe
