2.16

問：五戒八戒何者為勝？答：有因緣故，二戒皆等。但五戒終身持，八戒一日持。又五戒常持時多而戒少，一日戒時少戒多。復次若無大心，雖復終身持戒，不如有大心人一日戒也。譬如軟夫為將，雖將終身，智勇不足，卒無功名。若英雄奮發，禍亂立定，一日之勳，功蓋天下。

Question: Between the five precepts and the eight precepts, which is superior? Answer: Due to causes and conditions, both sets of precepts are equal. However, the five precepts are maintained for one's whole life, while the eight precepts are maintained for a single day. Furthermore, with the five precepts, the duration of constant observance is great while the precepts are few; with the one-day precepts, the time is short while the precepts are many. Moreover, if one lacks a great aspiration, even if one maintains the precepts for one's whole life, it does not compare to a person with a great aspiration keeping the precepts for a single day. For instance, if a weak man becomes a general, though he may lead an army for his whole life, his wisdom and courage are insufficient, and in the end he achieves no merit or fame. But if a hero exerts himself, disaster and turmoil are instantly quelled; the achievement of a single day surpasses the entire world.
