2.185

This refers to right effort, of which there are four. Namely, the four kinds of diligence prevent two unwholesome phenomena and gather two wholesome phenomena. That is to say: causing unwholesome phenomena that have already arisen to be abandoned, and causing those not yet arisen not to arise; causing wholesome phenomena not yet arisen to arise, and causing those already arisen to increase. The Mahāprajñāpāramitopadeśa states: 'The four kinds of diligence prevent the mind from being cowardly, lazy, shaken, fearful, or mistaken; therefore, they are called right effort.' The Abhidharma-nyāyānusāra-śāstra states: 'The reason why from beginningless time one has been unable to perceive the four noble truths is entirely due to laziness. Diligence can remedy this, enabling one to take joy in listening to and properly contemplating the principle of the four noble truths, and quickly realizing awakening.'
