大方廣佛華嚴經隨疏演義鈔 29.14

29.14

疏「言觀方謂觀四諦也」者，即《涅槃》三十六〈迦葉品〉中云「如恒河邊有七種眾生：一者沈沒；二者沒已還出、出已復沒；三者沒已却出、出已不沒；四者出已觀方；五者觀方已去；六者出去淺處則住；七者到彼岸。」廣有合文，今但取第四觀方一義。經云「是名第四遍觀四方，四方者即是四諦。」釋曰：能觀四諦即是道諦，故道名觀方。

Regarding the Commentary: "Speaking of 'observing the directions' refers to observing the four truths," this is what is stated in fascicle thirty-six, the "Kāśyapa Chapter" of the Nirvāṇa [Sūtra]: "Just as by the banks of the Ganges there are seven kinds of sentient beings: 1. those who sink; 2. those who, having sunk, emerge again, and having emerged, sink again; 3. those who, having sunk, come out and do not sink again; 4. those who, having emerged, observe the directions; 5. those who, having observed the directions, depart; 6. those who depart and abide in the shallows; 7. those who reach the other shore." There is extensive correlating text, but here only the single meaning of the fourth, observing the directions, is taken. The sūtra says: "This is called the fourth, universally observing the four directions; the four directions are none other than the four truths." The explanation says: being able to observe the four truths is precisely the truth of the path; therefore the path is named observing the directions.
