अत्स्यन्नं पश्यसि प्रियमत्त्यन्नं पश्यति प्रियं भवत्यस्य ब्रह्मवर्चसं कुले य एतमेवमात्मानं वैश्वानरमुपास्ते पादौ त्वेतावात्मन इति होवाच पादौ ते व्यम्लास्येतां यन्मां नागमिष्य इति ॥ ५.१७.२ ॥
In plain words
Thou eatest food and seest what is dear; and he eats food and sees what is dear, and the lustre of Brahman appears in his family, who worships this Self, Vaiśvānara, thus. But these are only the feet of the Self," he said. "Thy feet would have withered away, hadst thou not come to me."
The commentators
Chāndogyopaniṣadbhāṣyam· bhāṣya
अथ ह उवाच उद्दालकमित्यादि समानम् । पृथिवीमेव भगवो राजन्निति ह उवाच । एष वै प्रतिष्ठा पादौ वैश्वानरस्य । पादौ ते व्यम्लास्येतां विम्लानावभविष्यतां श्लथीभूतौ यन्मां नागमिष्य इति ॥
In plain words
Then he said, beginning with 'Uddālaka', the rest is identical: 'The earth indeed, revered sir, O king,' he said. This verily is the foundation, the feet of Vaiśvānara. Your two feet would have withered away, becoming shriveled and limp, had you not come to me.
