Fourfold Exersion/Application

From Zenwiki

(cattāri sammā-padhānāņi, catvāri samyak-pradhāņāni, 四正勤) is

  1. to decrease (existing) bad karma
  2. to not create (unborn) bad karma
  3. to start (unborn) good karma
  4. to increase (existing) good karma.

The Fourfold Right Severance/Deletion (cattāri sammā-pahāņāni, catvāri samyak-prahāņāni, 四正断) is misinterpretation or mis-attribution of the former, because there are 3) and 4) (starting and increasing, not only severing/deleting).
