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.
