___ (TLS, under v. 327, pp. 271-272)
This above Sanskrit passage needs exposition especially because Madhavacandra himself did not give any accompanying diagram which would have clarified our doubts.
8. EXPOSITION BY VISUDDHAMATI Aryikā Visuddhamati (1975) has written a useful commentary, in Hindi, on the TLS. In it, she exposes Madhavacandra's above passage with many tiny diagrams. The figure taken by her for a conch is the real, vide Fig. 6.
Without disturbing the exposition by Visuddhamati (pp. 273-276) the same with more explanation, well labelled diagrams and inevitable remarks which will be begun with "we would like to" is as follows:
The dimension of the deeply sunk conch in the Svayambhūramana ocean is 12 yojanas and the diameter of its circular face is 4 yojanas. This conch is not complete (musical) drum (muraja = mrdamga) in shape. Therefore,
if the debt (rna)
2 is added to it there, it becomes a complete drum
(sampurnamurajākāra) in shape, vide Fig. 7.
Here we would like to make clear that a 12 represents a cuboid of
2 which length, breadth and thickness are 2, 2 and 5/4 yojanas respectively.
We would like to call this
12 the first debt (FD).
