By learning to remain balanced in the face of everything experienced inside, one develops detachment towards all that one encounters in external situations as well. However, this detachment is not escapism or indifference to the problems of the world. Those who regularly practice Vipassana become more sensitive to the sufferings of others and do their utmost to relieve suffering in whatever way they can — not with any agitation, but with a mind full of love, compassion, and equanimity. They learn holy indifference — how to be fully committed, fully involved in helping others, while at the same time maintaining balance of mind. In this way they remain peaceful and happy while working for the peace and happiness of others.
This is what the Buddha taught: an art of living. He never established or taught any religion, any “ism.” He never instructed those who came to him to practice any rites or rituals, any empty formalities. Instead, he taught them just to observe nature as it is by observing the reality inside. Out of ignorance, we keep reacting in ways which harm ourselves and others. But when wisdom arises—the wisdom of observing reality as it is—this habit of reacting falls away. When we cease to react blindly, then we are capable of real action—action proceeding from a balanced mind, a mind which sees and understands the truth. Such action can only be positive, creative, helpful to ourselves and to others.
