Since all virtuous thoughts and actions motivated by clinging to a concrete reality or to a self-cherishing attitude are like poisonous food, give them up. Learn not to cling, but to know the phantomlike nature of experience.
One very powerful & effective way to work with tendency to push away pain & hold onto pleasure is the practice of tonglen. Tonglen is a Tibetan word that literally means “sending & taking.” The practice originated in India & came to Tibet in the eleventh century. In tonglen practice, when we see or feel suffering, we breathe in with the notion of completely feeling it, accepting it, & owning it. Then we breathe out, radiating compassion, lovingkindness, freshness; anything that encourages relaxation & openness.
