Tudubrahmasutta

Suttapiṭaka · Saṁyuttanikāya · Sagāthāvaggasaṁyutta · Vol. 15 · Section 597

[597] For when a person is born, an axe (kudhārī) is born in his mouth, with which the fool cuts himself, speaking ill-spoken words. He who praises one deserving blame, or blames one deserving praise, gathers with his mouth an unlucky throw (kali); through that unlucky throw he finds no happiness. Trifling is this unlucky throw — the loss of one's wealth at dice, even of all one has, together with oneself; this indeed is the greater unlucky throw: that one should corrupt his mind against the fortunate ones (sugata). For a hundred thousand nirabbudas, and thirty-six besides, and five abbudas, the reviler of the noble ones goes to hell, having directed evil speech and mind against them. The tenth: the Second Kokālika Sutta (Dutiyakokālikasutta).
