thank goodness for the Buddha's common sense and impeccable intention to bring clarity to us. As is recorded in the Vajjiputta Sutta:
"train in reference to those three trainings: the training in heightened virtue, the training in heightened mind, the training in heightened discernment"
these are the three divisions of the Noble Eightfold Path:
Heightened Discernment: best understanding and best intention
Heightened Virtue: best speech, best action and best livelihood
Heightened Mind: best effort, best mindfulness and best meditation
nothing is left out, nothing is unclear, persist and do your best, never forgetting the Buddha layed out GUIDELINES for our benefit, not rules.
