1.25

Third, seeing the Buddha by means of the light has two parts: first, seeing the Buddha; second, the descent of the three sages. Now, saying "within the light": this is Śākyamuni emitting the light of the tathatā of the dharmakāya; the light of wisdom illuminates, and depending on this dharmakāya one is able to see the response body. As for "the spiritual power of the Tathāgata": perhaps it is Śākyamuni's power, or perhaps Tathāgata simply refers to the dharma of tathatā; this tathatā has spiritual power, and relying on this spiritual power he comes, hence it is called spiritual power. Without moving from Vaiśālī, he reaches the place of Guangyan, the dharma realm of the true mark; abiding in this ground, he has pity on sentient beings in order to eliminate poisonous harms. The city is the dharma realm, taking its function of preventing wrongdoing. Resisting the enemy is the function of the city gate, which is the non-dual gate. Abiding unmoving in this gate, he enables sentient beings to enter this gate and reach the city of the dharma nature. As for "the golden color illuminating": tathatā is itself wisdom, reflecting back to illuminate the objective realm of tathatā.
