Now a passing reference may be made about the distance between two Suns always remaining diametrically opposite on both sides of Meru. In this context, SP.1.4 states as :
i.e. “When the two Suns tread upon the innermost (solar) mandala, they move 99640 yojanas apart from each other."
Here it is given that distance between two Suns moving on My=99640 y
= DM,
= Diameter of innermost solar mandala. A similar treatment holds good in case of any other solar mandala also. However this reveals the fact that the celestial angular distance between two Suns was measured in yojanas in terms of its corresponding distance projected along the surface of earth.
2. Lunar Mandala (Moon's Diurnal Circles):
It is fascinating to note that the theory of solar mandalas (Sun's diurnal circles) excercised a staunch impact upon the emergence of the parallel theory of lunar mandalas (lunar diurnal circles). Such an exordial note to the conclusiveness of the theory of lunar mandalas renders it more undeplorable and easily graspable. Besides, some short-out methods have been put in practice in order to avoid unnecessary repitition of mathematical logic for exposing the rationale of some aspects of theory of lunar mandalas parallel to those of theory of solar mandalas. Due emphasis has been laid upon the newness of lunar mandala theory in particular.
(i) Number of Lunar Mandalas (Lunar Diurnal Circles) :
There are 15 lunar mandalas. In this context, JP.7.17 states as :
“There are 5 lunar mandalas (diurnal circles) stretched over 180 yojanas in Jambudvipa. There are 10 lunar mandalas stretched over
