妙法蓮華經玄贊 2.173

2.173

贊曰：此一頌勤。此通被甲攝善二種，略無利樂有情精進。精進有五：謂被甲、加行、無下、無退、無足，即經所說有勢、有勤、有勇、堅猛、不捨善軛。最初發起猛利樂欲名被甲，次起堅固勇悍方便名加行，次為證得不自輕蔑亦無怯懼名無下，次能忍受寒熱等苦於劣等善不生喜足名無退，次能證入諸諦現觀等欣求後後勝品功德名無足。二乘究竟道欣大菩提故，諸佛究竟道樂利樂他故，初一名被甲，後四名攝善，此中合名「勇猛精進」。

Eulogy: This one verse praises vigor. This encompasses both armor-like vigor and the vigor that gathers wholesome qualities, while omitting the vigor that benefits and gladdens sentient beings. Vigor has five aspects: armor-like, application, non-inferiority, non-regression, and non-contentment; these correspond to what the sūtras describe as having power, having diligence, having courage, being firm and fierce, and not abandoning the yoke of goodness. First, generating intense and keen aspiration is called "armor-like"; next, arousing firm and brave expedient means is called "application"; next, for the sake of realization, neither despising oneself nor having timidity or dread is called "non-inferiority"; next, being able to endure sufferings such as cold and heat, and not giving rise to satisfaction with inferior goodness, is called "non-regression"; next, being able to enter the realization of the truths and seeking ever more superior classes of merits is called "non-contentment." Because the ultimate path of the two vehicles aspires to great bodhi, and the ultimate path of the buddhas delights in benefiting and bringing joy to others, the first one is called "armor-like" and the latter four are called "gathering wholesome qualities"; here they are collectively called "brave and fierce vigor."
