Visuddhimagga XI-113

Evaṃ sahajātādipaccayavasappavattāsu ca panetāsu dhātūsu –

如是由于俱生等的缘的力量而起的此等四界之中：

Ñ(XI,113): And when these elements have been made to occur through the influence of the conascence, etc., conditions:

Ekaṃ paṭicca tisso, catudhā tisso paṭicca eko ca;

Dve dhātuyo paṭicca, dve chaddhā sampavattanti.

以一界为缘而起三界有四种，

以三界为缘而起一界有四种，

以二界为缘而起二界有六种。

Ñ: With three in four ways to one due,

And likewise with one due to three;

With two in six ways due to two—

Thus their occurrence comes to be.
