Whenever a negative thought or emotion arises, remember the one who experiences these does not exist. Use the logic in the last post for conviction. HH Dalai lama explained this clearly in a short 8-min. video on dalailama.com — /videos/emptiness-and-compassion-as-antidotes-to-destructive-emotions.

When exchanging our selfish attitude for the attitude concerned with the wellbeing of others, i.e. Bodhicitta, negative karma is purified and positive karma is accumulated.
