The following is respectfully quoted from “Perfect Conduct” with commentary by Dudjom Rinpoche:
4.b.3(b.6) Disrespecting other religious philosophies and doctrines:
The sixth is criticizing the philosophical doctrines of heretics searching for a path, šravakas and pratyekas on the path, and the great path of Mahāyāna.
The first aspect of this downfall is to disrespect any Buddhist or non-Buddhist, especially if they are searching for a spiritual path and are practicing methods through which they can achieve spiritual understanding or freedom and if one has no intention of guiding them to a higher pursuit. The second is to disrespect those who have entered upon the path that renounces cyclic existence, such as the šravakas and pratyekas. In addition, the six root downfall concerns those who are on the great path of Mahāyāna, which eliminates the two extremes. To claim that the philosophies of these spiritual pursuits are untrue and pointless, and to then show blatant disrespect toward their practices, constitutes the root downfall.
