प्रवृत्तोऽश्वतरीरथो दासीनिष्कोऽत्स्यन्नं पश्यसि प्रियमत्त्यन्नं पश्यति प्रियं भवत्यस्य ब्रह्मवर्चसं कुले य एतमेवमात्मानं वैश्वानरमुपास्ते चक्षुषेतदात्मन इति होवाचान्धोऽभविष्यो यन्मां नागमिष्य इति ॥ ५.१३.२ ॥
In plain words
a chariot drawn by she-mules ready to go, a maidservant, a gold necklace. 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 this is only the eye of the Self," he said. "Thou wouldst have gone blind, hadst thou not come to me."
The commentators
Chāndogyopaniṣadbhāṣyam· bhāṣya
किंच त्वामनु प्रवृत्तः अश्वतरीभ्यां युक्तो रथोऽश्वतरी- रथः दासीनिष्को दासीभिर्युक्तो निष्को हारो दासीनिष्कः । अत्स्यन्नमित्यादि समानम् । चक्षुर्वैश्वानरस्य तु सविता । तस्य समस्तबुद्ध्योपासनात् अन्धोऽभविष्यः चक्षुर्हीनोऽभ- विष्यः यन्मां नागमिष्य इति पूर्ववत् ॥
In plain words
Moreover, the text 'A chariot drawn by mules... proceeds following you' is explained: a mule-chariot is a carriage yoked with two mules, and a gold-necklace with maids consists of gold ornaments together with female attendants. The interpretation of 'atsyannam' and what follows is identical to the previous section. However, the eye of Vaiśvānara is Savitṛ (the sun). Because of meditating upon it with complete understanding, you would have become blind—lacking sight—had you not come to me, exactly as stated before.
Close to the Sanskrit
Furthermore, a chariot yoked with two female mules proceeds following you—a mule-chariot; a gold-necklace with maids—equipped with maidservants, a necklace, a maid-necklace. 'atsyannam' etc. is the same. But the eye of Vaiśvānara is Savitṛ. From the worship of that with total understanding, you would have become blind—deprived of sight—if you had not come to me, as before.
