In some suttas only the first four precepts are mentioned, whereas all five precepts are described together in other suttas. The first four precepts are pakati-sila whereas the fifth precept is pannati-sila. Venerable Nyanatiloka explains in his Buddhist Dictionary that pakati-sila [is] natural or genuine morality, [which] is distinct from those outward rules of conduct laid down for either laymen or monks. Those latter are the so-called prescribed morality (pannatti-sila).
Suttas which include The Five Precepts are listed.
