[Buddha-l] Quoting Nagarjuna?

[Joy Vriens]

I found the following quote on http://indian-philosophy.braincells.com/

"When the fully enlightened teachers do not appear and when the disciples have disappeared, the wisdom of the self-enlightened ones will arise completely without a teacher."
- Naagaarjuna's Mulamaadhyamaka Kaarikaa (2nd century CE)

Is this a quote of Nagarjuna, MMK or elsewhere? I don't remember having read it.
