Buddha’s Teaching for human development is called “Four Noble Truths” (Kovács,
2001; Zeuschner, 2001).
The First Noble Truth: The Existence of Duhkha. All phenomena are inadequate and
unsatisfactory, and its nature is suffering from impermanence. If the nature of changing is not
understood, it will be the cause of pain, sorrow, and unhappiness, such as the basic situations
in everyone’s life: birth, aging, sickness, and death. In addition, to be with the unwanted, to
be detached from loved ones, and to be not fulfilled from desires are also painful.
