ديغا نيكايا 1:31
SUJATOKinti te, ānanda, sutaṁ, ‘vajjī apaññattaṁ na paññapenti, paññattaṁ na samucchindanti, yathāpaññatte porāṇe vajjidhamme samādāya vattantī’”ti?
Ānanda, have you heard that the Vajjis don’t make new decrees or abolish existing decrees, but proceed having undertaken the ancient Vajjian traditions as they have been decreed?”
