Buddha teaches the four noble truths:

The first of which states that suffering and frustration comes from our difficulty in facing the basic fact of life that everything around us is impermanent and transitory

"All things arise and pass away."

The second deals with the cause of suffering which is clinging or grasping of wrong points of view. Out of ignorance, we divide the perceived world into individual and separate things and thus attempt to confine the fluid forms of reality into fixed categories created by the mind

The third noble truth states that suffering and frustration can be ended. It is possible to free oneself from bondage and reach the state of total liberation

The fourth noble truth is Buddha's teaching to end all suffering through the path of self-development which leads to enlightenment. This is done through right seeing, right knowing, right action, right awareness, and right meditation
