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

, the म has a vertical stem! That vertical stem is part of 'म'!
So 'ह्मै' has the stem of 'म', and TWO slants on top: ै!
Then comes 'व': व!
Then in अशुद्धम्: comes 'त्र'? No, wait, in अशुद्धम्: 'ब्रह्मैव च चतुर्मुखः'?
Wait, look at अशुद्धम्:
The letters are:
ब् र ह्मै व ? Wait, look at the letter after ह्म:
Is it 'त्र'? Look at 'त्र': त्र has a diagonal down-left and a diagonal down-right from the vertical stem.
In row 25 अशुद्धम्:
After ह्म, there is 'त्र'!
Wait, why would it be त्र?
Could it be 'ब्रह्मैव' vs 'ब्रह्मैत्र'?
Wait, let's look at the letter:
It has an upper horizontal bar, a vertical stem, and two legs like 'त्र'! Yes, it is 'त्र'!
Wait, is there 'च' after it? Yes, 'च' is clearly there!
Then 'चतुर्मुखः'.
Wait, in शुद्धम्:
After 'ह्मै' (or ब्रह्मो):
There is 'व' and then 'तु'!
Wait, 'व' + 'तु' = 'वतु'!
So in अशुद्धम्: '...त्र च...'
In शुद्धम्: '...वतु...'!
Ah!
