梵網經菩薩戒本疏 5.8

5.8

Sixth, regarding light and heavy: With respect to the person, there are three: 1. If their understanding and practice surpass one's own, and they are an ācārya (model teacher), being arrogant and not respectfully requesting in principle should be heavy. 2. If their understanding and practice equal one's own, not requesting is somewhat light. 3. If inferior to one's own, not requesting is without offense. Second, with respect to the Dharma, there are also three, which can be understood by analogy with the person.
