CHĀNDOGYA UPANISHAD · 2.7.2

परोवरीयो हास्य भवति परोवरीयसो ह लोकाञ् जयति य एतद् एवं विद्वान् प्राणेषु पञ्चविधं परोवरीयः सामोपास्ते ।
इति तु पञ्चविधस्य ॥

parovarīyo hāsya bhavati parovarīyaso ha lokāñ jayati ya etad evaṃ vidvān prāṇeṣu pañcavidhaṃ parovarīyaḥ sāmopāste ।
iti tu pañcavidhasya ॥

What is greater than great belongs to him, nay, he conquers the worlds which are greater than great, who knowing this meditates on the fivefold Sâman, which is greater than great, as the prânas (senses).
