汝等比丘，若勤精进则事无难者，是故汝等，当勤精进，譬如小水常流则能穿石。若行者之心数数懈废，譬如钻火未热而息，虽欲得火，火难可得。是名精进。
释迦牟尼佛
《佛遗教经》
You [and] other Bhikṣus, if constantly diligent, [are] then [with] matters without difficulties. Therefore, you [and] others, should [be] constantly diligent. For example, like [a] small stream constantly flowing, [it is] then able [to] penetrate rock. If [the] minds [of] practitioners, [are] frequently lazy [and] abandon [practice], for example, like boring [for] fire, [with it] yet [to be] hot then resting, although desiring [to] obtain fire, fire [is] difficult to [be] obtained. [These] are named [as teachings on] diligence.
