Knowledge gained through hearing is not as wholesome as that gained through reading. Yet reading with the eyes is not as boundless as realizing through the mind. The best practice is to regard the mind as the sovereign, the eyes as ministers, and the ears as envoys. To let the eyes take up the role of the mind is an inferior approach, and to let the ears do the job of the eyes is the most inferior of all.
by Grand Master Lian Chi (蓮池大師), the Eighth Patriarch of Pure Land Buddhism
心得 – 錄自明末蓮池大師《竹窗隨筆》(初筆)
以耳聽受而得者，不如以目看讀而得者之廣也。以目看讀而得者，不如以心悟明而得者之極其廣也。以心為君、以目為臣、以耳為佐使，可也。用目當心，斯下矣。用耳當目，又下之下矣!
Buddha Mind
