बृहत्संहिता: द्वितीय भाग (आचार्य वराहमिहिर - विमला हिन्दी व्याख्या, पं. अच्युतानन्द झा)

' (i-matra going left)?
Wait, look at 'ती': does it have an 'ी' (long i)?
Yes, look at the curve over the top going to the right!
Wait, does it have a visarga?
No visarga visible after ती! It is "बहुविधमती"!
Wait, let's check meter:
ब (1) हु (1) वि (1) ध (1) म (1) ती (2) -> 1 1 1 1 1 2, then रन् (2) ध्र (1) वे (2) दी (2) प (1) रे (2) षाम् (2) = 17 syllables!
Yes, in Mandakranta, position 5-10 must be 1 1 1 1 1 2.
म-ध्ये क्षा-मो (2 2 2 2)
ब-हु-वि-ध-म-ती (1 1 1 1 1 2)
रन्-ध्र-वे-दी प-रे-षाम् (2 1 2 2 1 2 2)
So it MUST be "बहुविधमती" (with long ती to make it guru/heavy = 2)!
That's why it is "बहुविधमती", perfectly fitting the meter!
