Search on the Internet suggests there are 40 varan. However, there are passages which are not included in the 40 varas. What is the proof that there are just 40 varan?
The specific passage that I am referencing is:
kab laagai masathak charanan raja
dharas dhaeiaa dhrigan kab dhaekho |
anmrith bachan suno kab sravanana|
kab rasanaa baenathee bisaekho |
kab kar karo ddanddouth bandhanaa|
pagan farikramaadh pun raekho |
praem bhagath prathash praanapathi|
giaan dhiaan jhavinapadh laekho |401|
