"I understand that You teach Kalapa-vyakarana. I have heard that Your students are very expert in the word jugglery of this grammar."
There are many schools of grammar in the Sanskrit language, the most famous of which are the systems of Panini and the Kalapa and Kaumudi grammars. There were different branches of grammatical knowledge, and a student of grammar was supposed to study them all in twelve years. Caitanya Mahaprabhu, who was famous as Nimai Pandita, taught grammar to His students, who became expert in dealing with the word jugglery of complicated grammar.
