पूर्णप्रज्ञ भाष्य (श्रीमन् मध्वाचार्य - द्वैत वेदान्त ब्रह्मसूत्र महाभाष्य जगन्नाथदीपिका सटीक)

तु भवान्" = "May you, sir, revive her!"
Look at line 27:
"तु भवान् इत्येवमनुतापिनं तमभिलप्यापसरतेत्युक्त्वा हेरम्बोऽम्बि"
YES!
Line 26 ends with: "तामु...जीवय"
Line 27 starts with: "तु भवान्"!
"तामु[ज्]जीवयतु भवान्"!
The verb is definitely "उज्जीवयतु"!
With 'ताम्' (accusative of तद्, referring to the cow):
ताम् + उज्जीवयतु = तामुज्जीवयतु!
Now, why does 'ज्जी' look strange?
Let's look closely at 'तामुज्जीवय':
Is it 'तामुज्जीवय'?
Wait, what are the exact letters printed?
Let's inspect: 'ता', 'म' with 'ु' ('मु'), then:
Wait, is there an extra letter?
Look at:
ता (1)
मु (2)
Then a glyph: it looks like 'रु' or 'ज्'?
Then 'जी'? No, wait!
Could it be 'तामुज्जीवय'?
Wait, look at the glyphs:
ता | मु | [?] | जी | व | य
Let's count characters in line 26:
त (1) तो (2) ह (3) र (4)
