Mencius - Book 7, Part 1, Chapter 25

Mencius said, 'He who rises at cock-crowing and addresses himself earnestly to the practice of virtue, is a disciple of Shun.

'He who rises at cock-crowing, and addresses himself earnestly to the pursuit of giin, is a disciple of Chih.

'If you want to know what separates Shun from Chih, it is simply this, the interval between the thought of gain and the thought of virtue.'
