The phrase 'save the people and save the self', appeared in many Buddhist scriptures, the most famous of which was the Diamond Sutra. In the Diamond Sutra, Buddha taught that people should save others through their own strength and not rely on others. This concept was known as self-salvation, which meant solving problems and facing challenges by oneself. The Diamond Sutra also says that if we can initiate compassion and help to others, we can also obtain freedom and nirvana. Therefore, saving others and saving oneself became an important idea in Buddhism. It encouraged people to help others achieve self-transcendence and Nirvana through their own efforts and compassion.
