CHĀNDOGYA UPANISHAD · 2.1.4
स य एतद् एवं विद्वान् साधु सामेत्य् उपास्ते ऽभ्याशो ह यद् एनं साधवो धर्मा आ च गच्छेयुर् उप च नमेयुः ॥
sa ya etad evaṃ vidvān sādhu sāmety upāste ’bhyāśo ha yad enaṃ sādhavo dharmā ā ca gaccheyur upa ca nameyuḥ ॥
If any one knowing this meditates on the Sâman as good, depend upon it all good qualities will approach quickly, aye, they will become his own.
