The following is respectfully quoted from “Perfect Conduct” with commentary by Dudjom Rinpoche:
4.b.3(b.12) Causing someone to lose faith:
The twelfth is failing to accomplish the needs of any sentient being who possess the three levels of faith, failing to guard one’s own mind, and being deceitful.
The three levels of faith are these: inspired faith, which arises upon recalling the noble qualities of the lama and the Three Jewels; emulating faith, which is the wish to achieve those same qualities; and convinced faith, which is single-pointed devotion. If someone who possesses these three levels of faith needs or asks for spiritual assistance, to then ignore them when one has the potential to help them constitutes the twelfth downfall. In addition, failing to guard one’s mind and acting immorally, speaking unkindly, or deceiving someone so as to impair, damage or reverse their faith also constitutes the twelfth downfall.
