菩薩戒本疏 2.74

2.74

若佛子！初始出家未有所解，而自恃聰明有智，或恃高貴年宿，或恃大姓高門大解大福大富饒財七寶，以此憍慢而不諮受先學法師經律。其法師者，或小姓年少卑門貧窮，諸根不具而實有德，一切經律盡解。而新學菩薩不得觀法師種姓，而不來諮受法師第一義諦者，犯輕垢罪。

"If a disciple of the Buddha has newly left the household and does not yet have understanding, yet relying on being clever and possessing worldly wisdom, or relying on high and noble status or advanced age, or relying on great clan, noble family, great understanding, great merit, or abundant wealth and the seven treasures, out of such arrogance and conceit does not consult and receive the scriptures and vinaya from senior Dharma masters; and even if that Dharma master is of a lowly clan, young in years, from a humble background, poor, and deficient in the sense faculties, yet truly possesses virtue and completely understands all the scriptures and vinaya; yet the newly learning bodhisattva must not look at the Dharma master's social class and clan and fail to come consult and receive the supreme truth from the Dharma master—if they fail to do so, they commit a duṣkṛta offense."
