The fourth nobe Truth is the Way leading to the cessation of dukkha, and this is the eightfold Path. We come across the terms the development of the eight fold Path, the development of insight, vipassana, and the development of satipatthana or the four Applications of Mindfulness. All these terms pertain to the development of right understanding of mental phenomena, nama, physical phenomene, rupa. By the teaching of the four Applications of Mindfulness the Buddha showed that all namas and rupas which appear naturally in our daily life can be objects of mindfulness and right understanding.
