I've called my language school the Nagarjuna Language Institute for about 10 years. It's not really a good name for a couple of reasons.
I teach Classical Tibetan, a language into which Nagarjuna's works were translated, but so were lots of other authors. Positing the name of a language school in terms of an author whose works were translated into the language taught at the school seems, well, not all that well thought out.
