義若等者。謂闕之成謗、具之成門。成謗者，謂闕無成增益謗，闕有成損減謗，闕非有非無成相違謗，闕亦有亦無成戲論謗。以有則定有、無則定無，餘二例之，故成四謗。何以故？法不如是故，不如法見故。斯則般若波羅蜜猶如大火聚，四面不可取也。

[On the passage] "If the meaning...": this means lacking them becomes slander; possessing them becomes a gate. Becoming slander means: lacking nonexistence becomes the slander of superimposition; lacking existence becomes the slander of deprecation; lacking neither existence nor nonexistence becomes the slander of contradiction; lacking both existence and nonexistence becomes the slander of frivolous proliferation. Because existence would be definitively existent and nonexistence definitively nonexistent—the other two follow this pattern—they form four slanders. Why? Because dharmas are not like this, and one does not see according to dharma. In this case, prajñāpāramitā is like a great heap of fire, ungraspable on all four sides.
