Everybody has faults. Because we don’t like being criticised, we tend to hide our faults. If somebody points them out in a slight way, we become angry, and if somebody points them out in an even slighter way, we become even angrier. On the other hand, we think it’s our duty to point out others’ faults and to even criticise them in public. Although we don’t have exceptional qualities and there’s no reason to think that we’re better than other people, we think we are superior and are very proud of ourselves. Furthermore, we don’t practice, yet we call ourselves Dharma practitioners. It’s very cunning to try to deceive others by calling oneself a practitioner, and only few things are worse.
