吾生也有涯，而知也无涯。以有涯随无涯，殆已；已而为知者，殆而已矣。为善无近名，为恶无近刑。缘督以为经，可以保身，可以全生，可以养亲，可以尽年。
——《庄子 内篇 养生主第三》
汪榕培 英译:
Man’s life is limited but knowledge is unlimited. To pursue the
unlimited with the limited is fatiguing; to know this but still
pursue unlimited knowledge with limited life is fatal. When you do
good, don’t do it for the sake of fame; when you do bad, don’t do
it as to incur punishment. If you always keep to the proper way,
you will be able to keep a good health, preserve your nature,
support your parents and live out your full
life-span.
--Zhuang Zi Chapter 3 Essentials for Keeping a Good
Health
