Dhammapada · 4.7

Na paresaṃ vilomāni, na paresaṃ kaṭākataṃ;Attanova avekkheyya, katāni akatāni ca.

Na paresam vilomani, na paresam katakatam; Attanova avekkheyya, katani akatani ca.

Look not to the wrongs of others, nor to what others have done or not done. Look only to your own deeds — what you have done and have not done.

— Dhammapada 4.7
