In the “Magga Vibhanga Sutta” belonging to the “Magga Samyuktha” of “Samyuktha Nikaya”, our Gautama Buddha says,
“Dear Monks, what is the Noble Eightfold Path?…….
I would say that the Noble Eightfold Path is the practice of attaining the Nirvana, the end of all suffering. It has eight elements. They are: the correct vision, the correct thought, the correct speech, the correct behavior, the correct livelihood, the correct effort, the correct consciousness and the correct concentration.”
