Jaiminīya Upaniṣad Brāhmaṇa 3.30.3

3.30.3

pataṅgaḥ prājāpatya iti hovāca prajāpateḥ priyaḥ putra āsa
sa tasmā etat sāmābravīt
tena sa ṛṣīṇām udagāyat
ta eta ṛṣayo dhūtaśarīrā iti /

"Pataṅga Prājāpatya," he said, "was Prajāpati's beloved son. To him he spoke this sāman. With it he chanted the udgītha for the seers. Those seers [yonder] have had their bodies shaken off."
