Diamond Sutra, chapter 25
The lord Buddha continued:
"Subhuti, one should realize the egolessness of all things and understand selflessness. Why? because great disciples do not see merit as a personal possession, as something to be gained."
Subhuti asked, "What do you mean?"
The Buddha replied:
"Because great disciples do not seek merit, they do not see them as personal possessions, but they see them as the common possession of all beings."
It's important to remember that we are practicing the six perfections: generosity, patience, virtue, diligence, concentration and wisdom, not for ourselves and our own generation of merit, but for the good of all beings. When one being becomes Awakened, it truly helps all beings and makes the world a better place.
