Lesson 64 from A Comprehensive Commentary on the Words of My Perfect Teacher completes the ten negative actions by covering the three mental ones: covetousness, wishing harm on others, and wrong views.
On covetousness, a parable of a father reborn as a goose who provides for his impoverished daughter illustrates the point neatly — the moment she tries to capture him out of greed, he flies away forever, and a celestial being observes that covetousness destroys what it seeks. On wishing harm, the lesson is blunt: a person with a malicious mind will not be reborn in the Pure Land however much they recite Amitabha's name, and will attract harm from humans and non-humans alike. On wrong views, the lesson distinguishes eternalism — the belief in a permanent creator god — from nihilism, which denies karma, rebirth, and liberation entirely. The lesson identifies wrong views as the gravest of all ten negative actions, noting that even a single moment of wrong view breaks all vows and severs the path to liberation.
A Song Dynasty story of a butcher who leapt off a cliff in sudden remorse — and was saved by an auspicious cloud at the moment of impact — illustrates that even one instant of genuine repentance can purify boundless wrongdoing.
