एवं योऽयं दक्षिणेऽक्षन्पुरुषः, तस्य भूरिति शिर इत्यादि सर्वं समानम् ।तस्योपनिषत्- अहमिति, प्रत्यगात्मभूतत्वात् ।पूर्ववत् हन्तेः जहातेश्चेति ॥

In plain words

It works the same way for this person in your right eye — Bhūḥ is the head, and everything else follows exactly as before. His secret name is 'I', because he is nothing but your own inward self. And 'destroys' and 'abandons' carry the same meaning here as they did before.

Close to the Sanskrit

Thus, this person here in the right eye — 'Bhūḥ is the head' and so on, all of it is the same. His secret name is 'I', because he has become the inward self. As before, for [the verbs] 'destroys' and 'abandons'.
