Buddha said: Anger and ignorance are two of the three poisons.
Anger, due to suffering and suffering, aversion to hatred is the nature, which can hinder the absence of anger, unstable nature, and the basis of evil deeds is the karma. Anger is one of the fundamental defilements.
The so-called ignorance is ignorance. All the troubles in life and the disturbances of worldly affairs all arise from this.
