sutta citation style

[kirk5a]

On the Wikipedia entry for "nirvana" there are citations like this:

"'the liberated mind (citta) that no longer clings' means nibbāna" (Majjhima Nikaya 2-Att. 4.68).

How is the sutta reference number deciphered here? Can someone provide a cross-reference in the more typical style? Thanks!

It resembles

This is deathless: the liberation of the mind through lack of clinging/sustenance.'

from MN 106. Probably "2-Att" in that cite is referencing a commentary (atthakatha).

That's right. A commentary to the sutta says:

aññattha ca “anupādā cittassa vimokkho”ti nibbānaṃ vuccati.
Or elsewhere ‘the liberation of the mind through lack of clinging’ is called Unbinding (nibbāna).

Which is the quote from Wikipedia.

Excellent, thanks for the replies.
