On professions and living up to them. There are four ways
of professing a Doctrine:
- the first is unpleasant at the time and ripens to pain
thereafter,
- the second is pleasant at the time but also ripens to
pain,
- the third is unpleasant at the time but ripens to
pleasure,
- while the fourth is pleasant both at the time and
thereafter.
The Buddha then explains in detail these four classes of
profession. M.i.309 17.
