2.187

即心所法善十一中第十一法也○唯識論云。勇捍為性。疏云。勇而無怯。自策發也。捍而無懼。耐勞倦也○僧伽吒經云。欲求涅槃。當勤精進○十誦律序云。諸大德為道故。當一心勤精進。所以者何。諸佛一心勤精進故。得阿耨菩提。何況餘善道法○智度論云。有二精進。一身精進為小。二心精進為大。佛說意業大故。

This is the eleventh factor among the eleven wholesome mental factors. The Vijñaptimātratāsiddhi-śāstra states: 'Valiant boldness is its nature.' The commentary says: 'Being valiant without cowardice is to stimulate oneself; being bold without fear is to endure toil and fatigue.' The Saṃghāṭa-sūtra says: 'If one wishes to seek nirvāṇa, one must exert diligent vigor.' The preface to the Daśādhyāya-vinaya states: 'All Venerable Ones, for the sake of the Way, must single-mindedly exert diligent vigor. Why is this? Because all Buddhas, through single-minded diligent vigor, attain anuttarā-samyak-saṃbodhi—how much more so for the other wholesome teachings of the Way!' The Mahāprajñāpāramitopadeśa states: 'There are two kinds of vigor: physical vigor is minor, while mental vigor is major, because the Buddha taught that mental karma is great.'
