注大乘入楞伽經 6.43

6.43

言墮妄想自共見中，不了自心現量，計為有無，乃至虛妄分別離文字法，亦成壞者，是謂破壞佛法人也。

This means that falling into the parikalpa of individual and common views, failing to understand the direct perception of one's own mind, conceiving existence and non-existence, and even falsely discriminating phenomena that are detached from words, one also becomes a destroyer; this is what is called a person who destroys the Buddha's Dharma.
