Khaggavisāṇasuttaniddesa

Suttapiṭaka · Khuddakanikāya · Cūḷaniddesa · Vol. 30 · Section 817

[817] People associate with and resort to others for a motive; friends without a motive are hard to find today. Human beings are impure, their wisdom aimed at their own advantage. One should wander alone, like a rhinoceros horn.
