Chandogya Upanishad 4.74

स यदि यजुष्टो रिष्येद्भुवः स्वाहेति दक्षिणाग्नौ जुहुयाद्यजुषामेव तद्रसेन यजुषां वीर्येण यजुषां यज्ञस्य विरिष्टꣳ सन्दधाति ॥ ५ ॥

4.17.5 — sa yadi yajushto rishyedbhuvah svaheti dakshinagnau juhuyadyajushameva tadrasena yajusham viryena yajusham yajnasya virishtam sandadhati || 5 ||

If the sacrifice is injured from the Yagur-veda side, let him offer a libation in the Dakshina fire, saying, Bhuvah, Svâhâ! Thus does he bind together and heal, by means of the essence and the power of the Yagus verses themselves, whatever break the Yagus sacrifice may have suffered.

यदि यजुर्-वेद की ओर से टूट जाये, तो 'भुवः स्वाहा' कहकर दक्षिणाग्नि में आहुति दे — इस प्रकार वह यजुओं के ही रस तथा वीर्य से यजुः-यज्ञ की टूटन को जोड़ देता है।
