CHĀNDOGYA UPANISHAD · 2.1.3

अथोताप्य् आहुः ।
साम नो बतेति यत् साधु भवति साधु बतेत्य् एव तद् आहुः ।
असाम नो बतेति यद् असाधु भवत्य् असाधु बतेत्य् एव तद् आहुः ॥

athotāpy āhuḥ ।
sāma no bateti yat sādhu bhavati sādhu batety eva tad āhuḥ ।
asāma no bateti yad asādhu bhavaty asādhu batety eva tad āhuḥ ॥

And they also say, truly this is Sâman for us, i.e. it is good for us, when it is good; and truly that is not Sâman for us, i. e. it is not good for us, when it is not good.
