= The number of lunar sāvana days (moon-rises to moon-rises)
in a five-year cycle.
This indicates that the total number of lunar mandalas (lunar diurnal circles) in a five-year cycle has a one-one correspondence with the total number of sāvana days (a sāvana day means the period from moon-rise to moon-rise) in the same period (5-year cycle). Thus a lunar mandala (lunar diurnal circle) is traversed in a lunar sāvana day (moon-rise to moon-rise).
Velocity of Moon=1 lunar mandala/lunar sāvaņa day............(17)
Besides, it seems plausible that analogus to th part of the 15th lunar mandala (outermost lunar mandala), there must exist only the
th part of the first lunar mandala (innermost lunar mandala) upon which the Moon traverses its path in the northern part of Jambudvipa at about the ending moments of second-cāndrāyana (Moon's sidereal northern course) such that it again starts its southern journey while entering into the southern part of Jambudvipa as before. It is intended to impress upon here that there are 15 straps of lunar mandalas (lunar diurnal circles) and 14 spaces enclosed therebetween. Thus the Moon during its sidereal revolution moves twice upon 13 lunar mandalas and only once upon áth part of each of the extreme lunar mandalas viz. the 1st and the 15th.
(iii) Dimensions of Lunar mandalas :
As regards the dimensions of lunar mandalas, JP 7.21 states as :
“What are the diameter and the circumference of the innermost (lunar) mandala (lunar diurnal circle corresponding to Moon's extreme northern position) ?
"(The answer is) 99640 yojanas diameter and slightly more than 315089 yojanas circumference.
“What about second to the innermost mandala ?
