【馝（毘必）柯摩羅阿佚多】此云正勤。斯有四法，《法界次第》云：「一、已生惡法為除斷，一心精勤。四念處觀時，若懈怠心起，五蓋等諸煩惱覆心，離信等五種善根時，如是等惡若已生，為斷故，一心勤精進，方便除斷令盡也。二、未生惡法不令生，一心勤精進。四念處觀時，若懈怠心，及五蓋等諸煩惱惡法，雖未生，恐後應生，遮信等五種善根，今為不令生故，一心勤精進，方便遮止，不令得生也。三、未生善法為生，一心勤精進。四念處觀時，信等五種善根未生，為令生故，一心勤精進，方便修習，令信等善根生也。四、已生善法為增長，一心勤精進。若四念處觀時，信等五種善根已生，為令增長故，一心勤精進，方便修習信等善根，令不退失，增長成就。此四通名正勤者，破邪道，於正道中勤行，故名正勤也。」

[Vikrama-arādhitā (vīrya)] translates as right diligence (samyak-prahāṇa). There are four dharmas here. The Fajie cidi says: "1. Wholeheartedly exerting vigor to abandon and sever unwholesome dharmas that have already arisen. At the time of the contemplation of the four foundations of mindfulness, if a mind of laxity arises, the five hindrances and other afflictions cover the mind, and one is separated from the five wholesome roots such as faith, when such unwholesome things have already arisen, in order to sever them, one wholeheartedly exerts vigor, using expedients to eliminate and sever them completely. 2. Wholeheartedly exerting vigor to prevent unwholesome dharmas that have not yet arisen from arising. At the time of the contemplation of the four foundations of mindfulness, though a mind of laxity, the five hindrances, and other afflictive unwholesome dharmas have not yet arisen, fearing that they might arise later and obstruct the five wholesome roots such as faith, now in order not to let them arise, one wholeheartedly exerts vigor, using expedients to check them so that they cannot arise. 3. Wholeheartedly exerting vigor to bring about wholesome dharmas that have not yet arisen. At the time of the contemplation of the four foundations of mindfulness, when the five wholesome roots such as faith have not yet arisen, in order to cause them to arise, one wholeheartedly exerts vigor, using expedients to cultivate and practice so that the wholesome roots such as faith arise. 4. Wholeheartedly exerting vigor to increase wholesome dharmas that have already arisen. If at the time of the contemplation of the four foundations of mindfulness, the five wholesome roots such as faith have already arisen, in order to make them increase, one wholeheartedly exerts vigor, using expedients to cultivate and practice the wholesome roots such as faith, so that they do not regress and are brought to growth and fulfillment. These four are collectively called right diligence because they destroy heterodox paths and practice diligently within the correct path, hence they are called right diligence."
