Avatarika
एवमुक्तोपास्ये प्रागुक्तपदं व्याख्याय अथेदानीमुभयापेक्षया तृतीयमष्टमं च पदमुभयोपास्ये व्याख्यातुं देवप्रश्नः- अथ कस्मादुच्यते
In plain words
Having explained the earlier word in the meditation already described, the text turns — counting from both mantras — to the third word, the eighth position, shared by both forms of meditation, and the divine question opens: 'Now, why is it said...' [the record breaks off mid-question here]
Close to the Sanskrit
Thus, having explained the previously stated word in the [already] stated object of meditation, now, with reference to both, in order to explain the third — the eighth [word] — [common to] the object worshipped by both, [comes] the divine question: 'Now, why is it said...' [the sentence is incomplete in this record]
