7.34

解極等者。謂解極則心絕，心絕則會。如如體本周，故無方所，此明即應之真。

"The culmination of understanding," and so forth: This means that when understanding reaches its culmination, the mind ceases; when the mind ceases, there is convergence. Since the essence of tathatā is fundamentally all-pervasive, it has no spatial location; this clarifies the real that is identical to the responsive.
