大般涅槃經義記 7.423

7.423

自下第四舉空顯有，顯成向前第二段中舉空顯有。於中初言「唯有虛空無取作故能生一切」明空異有。無人取空，空不作物，名「無取作」。「以有因」下彰有異空，即事顯之。「尼𤘽陀子唯得住於尼𤘽陀樹」，不住餘樹，明知彼樹先有子性。此名樹果以之為子，非是種子。餘亦如是。

From here below, the fourth adduces space to reveal existence, revealing and establishing the adducing of space to reveal existence in the second section above. Therein, the initial statement, "Only empty space, having no taking or making, is able to produce all things," clarifies that space is different from existence. No one takes space, and space does not make things, hence it is termed "without taking or making." From "Because there is a cause" onward shows that existence is different from space, revealing it through concrete things: "The nyagrodha seed can only abide in the nyagrodha tree" and does not abide in other trees, which clearly shows that that tree previously had the nature of the seed. Here the fruit of the tree is termed a "seed," not the planting seed. The others are also like this.
