問：何因緣故，知佛世尊有此密意者，此第三難也。難意，佛說緣法處生意，法處定有。

"Question: By what cause or condition is it known that the Buddha, the World-Honoured One, had this intentional meaning?": This is the third part, the objection. The intent of the objection is: the Buddha said that the mind arises conditioned upon the dharma base, so the dharma base definitely exists.
