“Mendicants, those mendicants who are deceivers and flatterers, pompous and fake, insolent, and scattered: those mendicants are no followers of mine. They’ve left this teaching and training, and they don’t achieve growth, improvement, or maturity in this teaching and training. But those mendicants who are genuine, not flatterers, attentive, amenable, and serene: those mendicants are followers of mine. They haven’t left this teaching and training, and they achieve growth, improvement, or maturity in this teaching and training.

Those who are deceivers and flatterers, <j>pompous and fake, insolent and scattered: these don’t grow in the teaching that was taught by the perfected Buddha.

But those who are genuine, not flatterers, attentive, amenable, and serene: these do grow in the teaching that was taught by the perfected Buddha.”

Numbered Discourses 4.27 3. At Uruvelā Contentment

“Mendicants, these four trifles are easy to find and are blameless. What four? Rag-robes … A lump of almsfood … Lodgings at the root of a tree … Rancid urine as medicine … These four trifles are easy to find and are blameless. When a mendicant is content with trifles that are easy to find, they have one of the factors of the ascetic life, I say.
