All the words and attitudes of samsaric life, whether pleasant or unpleasant, kind or critical, are just the echoes of emptiness.... When we are complimented, we should leave aside the temptation to feel proud and simply regard the praise as if it were a dream or a fantasy.... As for criticism, it should be accepted and mixed with our Dharma practise in order to expose our hidden faults. As it is said: "Negativity and ill-treatment are the roots of the meditation flower. They are the Guru who destroys attachment and craving. Harsh words and blame spur us on toward discipline. How can we ever repay such kindness?"

-- Dilgo Khyentse Rinpoche
