仁王護國般若波羅蜜多經疏 3.308

3.308

解曰：初無相智者，謂真見道，無分別智證二空理，此最居初，故名初智。雖相見道，望脩為初，此在彼先，故名初也。照勝義諦者，證法性如二空所顯真勝義故。一相平等者，如智不二即一相平等。非相無相者，無能所相即非相無相。從此第三明所斷障。

Explanation: 'Initial signless cognition' refers to the true path of seeing, where nirvikalpa-jñāna realizes the principle of the two emptinesses; because this is at the very beginning, it is called the initial cognition. Although the path of seeing with characteristics is initial in terms of cultivation, this precedes that, hence it is called initial. 'Illuminates the paramārtha-satya' means realizing the thusness of dharmatā, the true paramārtha revealed by the two emptinesses. 'A single characteristic, equal' means that thusness and cognition are non-dual, which is a single characteristic, equal. 'Neither characteristic nor uncharacterized' means devoid of the characteristics of grasper and grasped, which is neither characteristic nor uncharacterized. Next, the third [part] clarifies the hindrances severed.
