Visuddhimagga XV-18

Tattha –

Atthato lakkhaṇādīhi, kama tāvatvasaṅkhato;

Paccayā atha daṭṭhabbā, veditabbo vinicchayo.

释此十八界：

一以义，二以相等，三以次第，四以限量，五以数，六以缘，七以所见而知于抉择。

Ñ(XV,18): Herein:

(1) As to meaning, (2) characteristic, et cetera, (3) Order, (4) just so much, and (5) reckoning, (6) Then condition, and (7) how to be seen—

Thus should be known the exposition.
