What is the core of Buddha’s teachings? 1. Refrain from all kind of sins. 2. Do good deeds. 3. Purify your mind. How can you purify the mind? And why is the mind considered dirty? The mind is considered dirty or impure because human beings always react with emotions such as anger, hatred, desire, craving and aversion. These emotions only make the mind unhappy. A purified mind looks clean and feels good. In order to purify the mind Buddha taught us to stop reacting emotionally. It means to just acknowledge without reacting, which requires a certain knowledge. This knowledge can be reached by the “Vipasana Meditation”.
