Life is like a dream, just like a river flowing eastward. All the joys and sorrows in the world are ultimately in vain. Living in this world requires extensive practice. Don't go against your body, mouth and heart and do ten kinds of evil causes, so as not to fall into hell and suffer from reincarnation. If the world can get rid of greed and selfish desires, it can enter a perfect realm. Everyone has Buddha nature, and realize this Buddha nature.
