Daisetz Teitaro Suzuki,
Essays in Zen Buddhism
(1927)
“ Those who have not seen into their own Nature, may read the Sutras, think of the Buddha, study long, work hard, practise religion throughout the six periods of the day, sit for a long time and never lie down for sleep, and may be wide in learning and well-informed in all things; and they may believe that all this is Buddhism. All the Buddhas in successive ages only talk of seeing into one’s Nature. All things are impermanent; until you get an insight into your Nature, do not say, ‘I have perfect knowledge.’ Such is really committing a very grave crime. ”
