The concept (of happiness) is universal. In Buddhism, it is called causeless joy, in Christianity, the kingdom of heaven within, and in Judaism it is called ashrei, an inner sense of holiness and health. Is Islam it is called falah, happiness and well-being, and in Hinduism it is called ananda, or pure bliss.
