佛說觀普賢菩薩行法經 1.65

1.65

"If an upāsaka violates deportment and commits unwholesome deeds—the unwholesome deeds being speaking of faults and evils in the Buddha-Dharma, discussing the misdeeds committed by the fourfold assembly, and engaging in theft and sexual misconduct without shame or remorse—if they wish to repent and extinguish all sins, they should diligently read and recite the vaipulya sūtras and contemplate the ultimate truth.
