sentences:  Built on the insightful recognition of the arising and non-arising of various mental qualities over time and of our ability to mindfully intervene in these ephemeral qualities, the Four Right Exertions encourage the relinquishment of harmful mental qualities and the nurturing of beneficial mental qualities.The Four Right Exertions are associated with the Noble Eightfold Path's factor of "right effort" ("sammā-vāyāma") and the Five Spiritual Faculties' faculty of "energy" ("viriya"); and, are one of the seven sets of Qualities Conducive to Enlightenment.The Four Right Exertions are found in the Vinaya Pitaka, Sutta Pitaka, Abhidhamma Pitaka and Pali commentaries.
