And it also leads us to realize the value and dignity of human being because Buddhist philosophy holds that the perfect human being must be endowed with two important qualities ; namely, right knowledge and right action which are useful to oneself and his society. This is certainly the virtue of the Buddha. So the motto of the Buddhists is “Knowledge must be coupled with virtue” Buddhist philosophy holds that man can have perfect freedom in so for as he can use wisdom to realize all things in order to eradicate his defilements by not allowing his mind go under the influence of any defilement and by lifting it up to the state of real liberation. The real freedom is certainly the “Free will of the enlightened ones or Arahantas” About doing something good to society Buddhist philosophy has shown the way for human being to use his capacity and intelligence to behave himself nicely and morally. That is to perform his human duties uttermost in order to bring about benefits to society as much as possible. Especially the Buddhist principles of “Service” (Sangahavatthu Dhamma) and the virtures of sublime life (Brahmavihara Dhamma) aim at making group integration and social relation among human beings in order to achieve inter recognition to reduce selfishness and conflicts about equilibrium in various aspects such as political, economical and social etc.
