仁王般若經疏 1.65

1.65

As for the text saying "reflecting on conditions," the arising of the greatest teaching is conditioned by the clear discernment of great wisdom; hence it says "reflecting on conditions." Another explanation is: "reflecting on conditions" means that, wishing to expound prajñā, he reflects on the meaning of marklessness. "Conditions" means taking tathatā and the principle of dharmatā as object-condition. From "emitted a great bright light" downward is the second [section] within the occasion of expounding the sūtra, explaining the emission of light. A "great bright light" is the manifestation of a rare event, causing those who do not yet have faith to generate faith, and causing those who already have faith to gain increase; it is also intended to cause sentient beings to destroy the darkness of ignorance and obtain the light of wisdom. There are two kinds of light: first, the light of supernormal powers; second, the light of wisdom. Why did he emit the light of supernormal powers? The various children who have the conditions are scattered across the ten directions; if he did not emit light to summon and gather them, they would not know the causes and conditions for expounding prajñā; therefore he emitted light. Distinguishing the characteristics of dharmas to accord with beings' faculties and capacities, he therefore emitted the light of wisdom. "Illuminated the three realms" refers to the reach of the light. "Furthermore, from the crown of his head, a lotus" is the third supernormal power. Some have their capacities stimulated upon beholding the light, while others gain benefit upon seeing the flower; therefore he manifested the flower. "Ascended up to [the heaven of] neither-perception" refers to where the flower reached. This sūtra explains that the formless realm possesses form. "The light was also like this" means it was the same as the flower. "Reaching as far as the other directions" means that it not only illuminated this region, but also pervaded the ten directions. "Buddha-lands numerous as the sands of the Ganges" expresses that the path of transformation is mutually connected.
