6.3

“Yāvakīvañca, ānanda, vajjī apaññattaṃ na paññāpessanti, paññattaṃ na samucchindissanti, yathāpaññatte porāṇe vajjidhamme samādāya vattissanti; vuddhiyeva, ānanda, vajjīnaṃ pāṭikaṅkhā, no parihāni.

“As long as the Vajjis don’t make new decrees or abolish existing decrees, but proceed having undertaken the ancient Vajjian principles as they have been decreed, they can expect growth, not decline.
