Selfishness is the main cause to create all negative for self and others

What causes all the troubles and misunderstanding, unhappiness is so-called “selfishness”. Because our nature is ordinary people, we are so much self-centered people. We put ourselves in the best and in the very center and then we try to serve, we try to do anything we can for oneself. We try our best to make oneself happy, to make oneself famous, rich v. v. But that is not a correct way to make oneself very happy, because of the self being in the center we are too much selfish. Therefore, train one’s mind through Bodhicitta motivation, through loving kindness, through compassion. Try to eliminate this such strong desire to the self. Try to subdue their attachment to the self. And try to understand it is important to see others important, to try to benefit others.
Whenever, for any reason, one is being very self-centered, one is creating a lot of problems for oneself. Because self-centered-ness is an idea of seeing the importance of self and it produces a lot of poison in the mind. Selfishness is the main cause to create all negative emotions, three poisons or five poisons. Therefore, as long as one is being self-centered person, then one is having a lot of this mental distraction, having a lot of attachment, ignorance, anger, pride, jealousy and so on.
