2.229

唯一堅密身，一切塵中見。義曰：二四唯遍義，五唯容義。今合之同時，具此二義也。一法望多時，雖普遍而即廣容也；多法望一法時，攝一法在多法中，雖廣容而即普遍也。遍即容、容即遍，故曰無礙。

In only one firm and dense body, / It is seen in all dust motes. The meaning is: the second and fourth [gates] have solely the meaning of pervasion, while the fifth has solely the meaning of containment. Now combining them simultaneously, it possesses both of these two meanings. When viewing one dharma in relation to the many, while it universally pervades, it immediately broadly contains; when viewing many dharmas in relation to one dharma, gathering one dharma within the many dharmas, while broadly containing, it immediately universally pervades. Pervasion is containment, and containment is pervasion; hence called 'unobstructed'.
