14.337

基云：如俱舍名隣阿伽色，阿伽是極礙，此色隣彼，即此中依止聲色等處而有空界色等處，而有空界。

Ji says, "As the Abhidharmakośa calls it 'form adjacent to aghana'—aghana meaning ultimate obstruction, and this form being adjacent to that—it is precisely here that, depending on places of sounds, forms, and so on, there is space realm form, and depending on such places there is the space realm."
