You have to remember buddha nature. In the emptiness of your heart, remember you have buddha nature. Delusions are not permanent, they are not part of you, they are temporary. You can be free from delusions and negative karma. Like a mirror covered by dust, you can clean it. The more you clean it, the clearer the reflection becomes. Your mind becomes clearer the more the delusions are purified.

-- Lama Zopa Rinpoche
