4.246

These are all the arising of conditions and manifestations of the dharma gate of nirvāṇa, and cannot be apprehended merely as literal facts. Therefore, when the assembly below knows and sees this matter, it is called knowing the dharma-nature and experiencing dharma-pleasure. This concludes the first section.
