Bhagaval 5:1:3-12 of Mount Meru. When there is day-time in the East and West parts of Mount Metu, there is the night-time in the North and South parts.
When the longest day is eighteen muharttas, the night is twelve muharttas, because there are thirty muhurttas in a diurnal period. The shortest day is twelve muhürttas, and at that time, the night is eighteen muhürttas. The sun completes one mandala' (diurnal circle) in sixty muhürttas. The largest day is of eighteen muhurttas, and therefore, 18 muhurttas is equal to 18" part of 60 muhurttas that is, "="" When the day is of 18 muhurttas, each sun lights part of the Island of Jambudvipa. The circumference of Island of Jambudvipa is 316228 yojanas. " of that circumference is
10
316228 x
94868 / yojanas.
This is the lit field of Island of Jambudvipa.
The perimeter of Mount Meru is 31623 yojanas. The lit field of Mount Meru is of this perimeter, that is 31623 x 10
9486
yojanas.

The shortest day is 12 muhürttas, which is part of sixty muhurttas. The circumference of Island of Jambudvipa is 316228 yojanas. In the shortest day, the lit field of Island of Jambudvipa will be part of that circumference. It is = 61245 yojanas.
The perimeter of the Mount Meru is 31623 yojanas. The lit field of Mount Meru on the shortest day is
31623 x 6324" yojanas.
2,0 10
In length, the lit field of the Island of Jambudvipa is 45000 yojanas2 and that of the Lavana Ocean is 33333, yojanas. When these both are added, the total comes to 45000 +33333,, that is, 78333, yojanas. (See figure on p. 710).

When the longest day is of eighteen muhurttas, the sun is in its inner circle (mandala). When the shortest day is twelve muhürttas, the sun is in their outer circle (mandala). The sun starts it journey towards the south from the inner muhurtta circle and that period is called southern solstice (winter solstice). When the sun starts it journey from the outer muhurtta circle towards the north it is called summer solstice. In one solstice the sun has to cross 183 circles. The difference between the largest and the shortest day time is 18- 12 that is six muhurttas. The sun takes six muhurttas to cross 183 circles and therefore it takes /,,, muhurttas to cross one mandala. When the sun crosses from the innermost circle to the outermost circle, the length of the day-time is 18-17 59, muhurttas, and at that time the length of the night-time is 12+2 = 12 muhurttas. The length of the night-time increases in proportion to decrease in the length of day-time, because the total of the length of day-time and the night-timem increases in proportion to is thirty muhurttas. Every day there is increase or decrease of 3 muhurttas in the length of the day-time. When the length of the day time is seventeen muhurttas that of the night-time is thirteen. There is decrease or increase of one muhurtta when the sun crosses 30, mandalas", mandalas. There is thus decrease of muhurttas in one mandala.
