Nagarjuna

https://en.wikipedia.org/wiki/Nagarjuna
There is two modes of knowing:
- relative truth
- ultimate truth
  - [ken wilber] says prajna / gnosis / knowledge are all related (jn/gn/kn)
You can't use the relative mind to think of the ultimate.
- Demonstrated that for every concept X, ultimate reality is;
  - not x
  - not not x
  - not both
  - not neither (?)
- "not even wrong"
