慈氏菩薩云：應告彼言：何者世俗？何者勝義？如是問已。彼清辨等答曰：一切依他法皆無自性，是名勝義；若無自性中，因緣自性可得，是名世俗。何以故？實無所有中建立世俗有法，假設名言而起言說，故名為世俗。

Maitreya Bodhisattva says: One should say to them: 'What is conventional? What is ultimate?' Having asked this, Bhāviveka and others answer: 'All paratantra dharmas have no intrinsic nature; this is called the ultimate. If within what has no intrinsic nature, an intrinsic nature of causes and conditions can be obtained, this is called the conventional. Why is this? Within what truly does not exist, conventional existent dharmas are established, provisionally positing names and words to give rise to discourse; therefore it is called conventional.'
