If one's own wisdom is low, then even when relying on the teachings, one is actually unable to rely on them, because one cannot understand the teachings and does not know their true meaning and direction; one will often misunderstand the teachings and misinterpret them. Relying on such misinterpreted teachings and then comparing them against what others say, the frame of reference is wrong, so the result of the comparison is of course erroneous, and one cannot accurately judge whether what others say is correct or not.
If one's wisdom is low, then even if one wants to rely on the Dharma, one has no way to do so; likewise, one cannot judge the true meaning and direction of the Dharma principles. One either misunderstands the Dharma principles or only vaguely fails to understand them; one cannot comprehend the Dharma meanings expounded by others and cannot truly understand them. In this way, one cannot accurately judge whether what others say is correct or not, and one gains no benefit from the Dharma. Moreover, if one is fond of thrusting oneself forward and passing judgments everywhere, it is easy to create the karma of slander, which not only obstructs one's own progress on the Path but also brings the evil retribution of foolish slander. Therefore, while one's wisdom is still insufficient, one should bury oneself in study and practice, refrain from judging any Dharma or any person, be a wise person, refrain from creating evil karma, and avoid receiving evil retribution.
