an.2.43 Aṅguttara Nikāya (Numbered Discourses)

43
“There are, mendicants, these two assemblies.
What two?
A divided assembly and a harmonious assembly.
And what is a divided assembly?
An assembly where the mendicants argue, quarrel, and dispute, continually wounding each other with barbed words.
This is called a divided assembly.
And what is a harmonious assembly?
An assembly where the mendicants live in harmony, appreciating each other, without quarreling, blending like milk and water, and regarding each other with kindly eyes.
This is called a harmonious assembly.
These are the two assemblies.
The better of these two assemblies is the harmonious assembly.”
