7.258

答：第二劫中，前六有相，第七無相，且有、無相相對名「二」。於有相中略而不言，示方隅爾。

Answer: In the second aeon, the first six have signs, while the seventh is signless. For the time being, having signs and being signless are paired to be called "two." Among those with signs, it is omitted and not spoken of, merely indicating the general outline.
