第四色、空章十門止觀者。
The Fourth: The Ten Gates of Contemplating Emptiness Through Calm and Insight.
第一會相歸性門，於中，有二種：一、於所緣境會事歸理。二、於能緣心攝將入正也。
The First Gateway: Returning Phenomena to Their True Nature
Within this, there are two aspects:
First, regarding the objects of perception: merging all phenomena back into their underlying principle.
Second, regarding the perceiving mind: gathering and directing it toward what is truly right.
第二依理起事門者，亦有二種：一者、所歸理非斷空故，不礙事相宛然。二者、所入止不滯寂故，復有隨事起修妙覺觀。
The second gate is establishing phenomena based on principle, which also has two aspects: First, the principle we rely upon is not mere emptiness; therefore, it does not obstruct the vivid manifestation of phenomena. Second, the stillness we enter does not stagnate in quiescence; thus, there is also the wondrous contemplation of awakening that arises in accordance with phenomena.
第三理事無礙門者，亦有二種：一、由習前理事能通交徹，故今無礙也。二、雙現前故，遂使止觀同於一念頓照故。
The third gateway is the unimpededness of principle and phenomena. This also has two aspects:
First, through practicing the previous understanding of principle and phenomena, one can penetrate and illuminate them mutually, thus achieving unimpededness.
Second, since both are simultaneously present, it enables cessation and contemplation to unite in a single moment of immediate, complete illumination.
第四理事雙絕門者，由事、理雙觀互相形奪故，遂使而雙俱盡，非理非事，寂然雙絕，是故令止觀雙泯，逈然無寄也。
The fourth gate is the simultaneous cessation of phenomena and principle. By observing both phenomena and principle together, they mutually negate each other. As a result, both are completely exhausted—neither principle nor phenomena remain. In this serene, dual cessation, both stillness and insight vanish, leaving nothing to grasp.
第五心境融通門者，即彼絕理事之無礙境，與彼泯止觀之無礙心，二而不二，故不礙心境；而冥然一味，不二而二，故不壞一味，而心、境兩分也。
第六事事相在門者，由理帶諸事全遍一事，是故以即止之觀，於一事中現一切法，而心無散動。如一事，一切亦爾。
第七彼此相是門者，由諸事悉不異於理，理復不異於事，即是一切而念不亂，如一事一切亦爾。
第八即入無礙門者，由交參非一與相含非異，體無二故，是故以止觀無二之智頓現，即入二門同一法界，即心無散動也。
第九帝網重現門者，由於一事中具一切，復各具一切，如是重重不可窮盡。如一事既爾，餘一切事亦然。以止觀心境不異之目頓現一切，各各重重悉無窮盡，普眼所矚，朗然現前而無分別，亦無散動也。
第十主伴圓備門者。菩薩以普門之智，頓照於此普門法界。然舉一為主，一切為伴，主伴、伴主皆悉無盡，不可稱說，菩薩三昧海門皆悉安立自在無礙，然無異念也。
