The Ten Precepts - explained in Nagarjuna's Great Discourse on the Perfection of Wisdom

These ten precepts, explained in Nagarjuna's Great Discourse on the Perfection of Wisdom (S. Maha Prajna Paramita Sastra, C. Ta-Chih-Tu Lun, J. Dai Chi Do Ron), are further elaborated by Chih-I in the fourth volume of The Great Calm-Observation (C. Mo-Ho Chih-Kuan, J. Maka Shikan).

The lower precepts are likened to the master potter's making of vessels, symbolizing the spiritual vessel that can hold and serve the Dharma.
