釋摩訶衍論 4.6

4.6

牟尼大覺尊，一代聖說中，
總有六種說，謂明闇俱非，
空及與具足。如是六無明，
隨義立異名，剋體無差別。

In the lifetime holy teachings of Muni, the Great Awakened Honoured One,
There are altogether six kinds of teachings:
Namely bright, dark, both, neither,
Empty, and fully endowed.
These six kinds of avidyā
Are established with different names according to their meanings;
Determined in substance, they have no difference.
