Article Count Progress

We have reached 0% of our goal of 10100 articles.


Counting this way for unspeakable eons,
Using unspeakable numbers,
Counting eons by these atoms,
One atoms standing for ten myriad unspeakable numbers of eons,
If you praise a single Universally Good for that many eons,

It would still be impossible to exhaust the amount of virtue of Universal Good.
  —from the Avatamsaka Sutra
