五、大精進力：雖佛道長遠不以為遙，雖眾生數多而意有勇。心堅無退，精進發趣，初無疲怠。是名「五緣」。

Fifth, the power of great vigor: although the Buddha path is long and distant, one does not consider it far; although sentient beings are numerous, one's mind has courage. With a firm, non-retrogressing mind, one sets forth with vigor, completely free from fatigue and remissness from the start. These are called the 'five conditions.'
