金剛般若經旨贊 1.34

1.34

[Sūtra:] "Subhūti, ... can it be thought of?"
[Commentary:] The following repeatedly exemplifies the remaining nine [directions]. The text is likewise divided into two; this is the first, the Buddha's question. Adducing the eastern direction beforehand was already sufficient to make manifest the vastness of merit; questioning again about the remaining nine demonstrates that the benefit is even greater. However, as for space, it is named for its unobstructedness; in truth, it cannot be said to possess spatial locations. Yet adapting to material forms, the ten directions are provisionally spoken of; for if there were no material form, there would be no space. The term "the four intermediate directions" refers to the four corners. The rest of the text is easy to understand, so it is not explained at length.
