Why and how the self restrain important and find relevant suttas in the Ti Pitaka that the Buddha talked about.

There are many suttas that talks about the importance of self restrain some on the suttas like satipatthana sutta, Mahasatipatthana sutta, Muni Sutta, Dhammapada and etc.

Buddhism is a religion of tolerance because it preaches a life of self-restraint. Buddhism teaches a life based not on rules but on principles. Hatred does not cease by hatred; by love alone does it cease.' Such is said by the Buddha for welfare of one and others. Even the first verse of the Dhammapada says thus:

All states have mind as their forerunner, mind is their chief, and they are mind-made. If one speaks or acts, with a defiled mind, suffering follows one even as the wheel follows the hoof of the draught-ox. So we see that Buddha has always asked to keep control. In order to overcome greed, hatred, and delusion, a person needs to change not only his or her personal conduct or lifestyle, but also the system that creates them. The Five Precepts shown by the Buddha also talks about self control. Buddhists never really stops studying the suffering of oneself and that of other people. This forms a central focus of the religion, its practice and its philosophy so to study about suffering one must experience suffering though limited self control. Buddhism is a religion of self-transformation and self-improvement, through application of continuous effort of self control. Muni sutta says thus about self control

 “Self-restrained, he does no evil. Young and middle-aged, the sage self-controlled, never angered, he angers none: The enlightened call him a sage.” Even Buddhavagga of Dhammapada says what all the Buddhas say about restraint thus: Sabba paapassa akaranam kusalassa upasampada saacitta pariyoda panam etam buddhaano sasanam, Avoid all evil or akusala deed with restrained mind and purify your mind this is the teaching of all the Buddhas. This stanza is to show the importance of self development for everyone. Self development means personal responsibility for one’s own learning and development through a process of taking action. According to satipatthana sutta we have develop our mind through meditation. Sitting meditation and mindfulness will help each and every being to become more loving, compassionate, joyous, composed, generous, disciplined, patient, courageous and mindful. Buddha even in his death bed said that appamadena sampadetha. Live diligently and develop yourself. A fully integrated liberated person has a very self controlled and development.
