Sangitisutta 3.3.89

3.3.89

Tattha sabbeheva saṅgāyitabbaṃ na vivaditabbaṃ, yathayidaṃ brahmacariyaṃ addhaniyaṃ assa ciraṭṭhitikaṃ, tadassa bahujanahitāya bahujanasukhāya lokānukampāya atthāya hitāya sukhāya devamanussānan”ti.

You should all recite these in concert, without disputing, so that this spiritual path may last for a long time. That would be for the welfare and happiness of the people, out of sympathy for the world, for the benefit, welfare, and happiness of gods and humans.”
