"What about third to the innermost mandala ?
41
"99785+×) yojanas diameter and slightly more than
61 315549 yojanas circumference.
"So likewise when the Moon goes on advancing, the diameter goes on 51 increasing by 72+) yojanas per mandala and the circumference increases by 230 yojanas per mandala.
"What about the outermost (lunar) mandala (lunar diurnal circle corresponding to Moon's extreme southern position) ?
"1006600 yojanas diameter and 318315 yojanas circumference."
One may find at first sight that dimensions (diameter and circumference only) of the extreme lunar mandalas (innermost lunar mandala and outermost lunar mandala) are exactly the same as those of the corresponding extreme solar mandalas (innermost solar mandala and outermost solar mandala). Therefore distances of the extreme lunar mandalas from periphery of Meru's base on flat earth are also the same as those of the corresponding extreme solar mandalas. The dimensions (diameter, circumference, NPD from Meru) of lunar mandalas other than extreme ones are generated alike to the computation of those of the similar (other than extreme one) solar mandalas. However it is to be noted that we are given that
Rate of change of diameter of lunar mandalas
=725+) Yojanas/lunar savaṇa day (time taken by Moon to traverse one lunar mandala).
Rate of change of radius of lunar mandalas
=7281+(4) Yojanas/lunar sāvaṇa day..
..(18)
Since the radius increases 14 times (corresponding to 14 spaces between extreme lunar mandalas) till the Moon occupies 15th lunar mandala in its southern journey and vice versa, so total change (increase or decrease) of radii of lunar mandalas
