At Sāvatthī.

“Mendicants, sentient beings come together and converge because of an element: the imprudent with the imprudent … unlearned … witless. The prudent with the prudent … learned … wise.

… the imprudent with the imprudent … lazy … witless. The prudent with the prudent … energetic … wise.

… the imprudent with the imprudent … unmindful … witless. The prudent with the prudent … mindful … wise.”
