仁王護國般若波羅蜜多經疏 2.98

2.98

解曰：言三有者，欲有、色有、無色有也。言業果者，業謂有漏善、不善業，及煩惱障，緣助力故。果謂所感諸趣異熟身命短長，隨因緣力有定齊限分段果故。一切皆空者，彼無自性，皆空無也。從此第二結無明空。

The commentary explains: The 'three realms of existence' refers to the realm of desire, the realm of form, and the formless realm. 'Karmic fruits': 'karma' refers to tainted wholesome and unwholesome karma, aided by afflictive obscurations acting as contributing conditions; 'fruits' refers to the resultant lengths of life and types of rebirth in various destinies, which, being bounded by fixed limits according to the power of causes and conditions, constitute the fruits of portioned [existence]. 'All entirely empty' means that they lack intrinsic nature (niḥsvabhāva) and are all empty and nonexistent. Next is the second section, concluding that ignorance is empty.
