Tlie same result, viz., to find the place of the moon on a given parvan 

 is obtained by following another rule contained in some gathas quoted by 

 the commentator. Their purport is as follows. Multiply sixty-seven (the 

 number of periodical revolutions which the moon makes during one yuga) 

 by the number of the parvan the place of which you wish to find and divide 

 this product by one hundred and twenty-four (the number of par vans of 

 one yuga). The quotient shows the number of whole revolutions the moon, 

 has accomplished at the time of the parvan. The remainder is to be multi- 

 plied by ISyO {viz., 1830 sixty-sevenths which is the number of nycthe- 

 mera of one periodical month) or more simply by 9L5 (reducing 1830 as 

 well as the denominator viz., 121 by two). From the product (remainder 

 multiplied by 9i5) deduct 1302, which is that part of a whole revolution

which is occup)ied by Abhijit (Abhijit occupies — days, but as this amount 



is to be deducted from the numerator of a fraction the denominator of 

 which is 62, 21 is to be multiplied by 62 ; product = 1302). The portion 

 of Abhijit, from which the moon's revolutions begin, is deducted at the 

 outset, because it is greatly smaller than the portion of all other naksha- 

 tras and would disturb all average calculations. After it is has been de- 

 ducted the remainder is divided by 67 X 62 ; the quotient shows the 

 number of nakshatras beginning from S'ravana which the moon has passed 

 through, in addition to the complete revolutions. The I'emainder is again 

 multiplied by thirty, the product divided by 62 ; the quotient shows the 

 number of muhiirtas during which the moon has been in the nakshatra in 

 which she is at the time. And so on down to small fractions of nakshatras. 

 The following is an example. Wanted the place of tlie moon at the end of the 

 second parvan. Multiply 67 by 2 ; divide the product by 121. The quo- 

 tient (1) indicates that the moon has performed one complete periodical 

 revolution. The remainder (10) is multiplied by 1830 or more simply by 

 915 (see above); from the product (9150) the portion of Abhijit (1302) 

 is deducted. The remainder (7818) is divided by 67 X 62 = 4151 ; the 

 quotient (1) shows that after Abhijit the moon has passed through one 

 complete nakshatra, viz., S'ravana. The remainder (3091) is multiplied by 

 80 ; the i^roduct (110820) again divided by 1151 ; the quotient (20) shows 

 that tiie moon has moreover passed through 26 muhurtas of S'ravishtha. 

 By carrying on this calculation we arrive at the result that at the end of 

 the second parvan the moon stands in S'ravishtha, of which she has passed

tiirough 26 -I- + — muhurtas.

Analogous calculations are made for the sun too. For instance, in 

 what circle does the sun move at the time of each parvan ? The rule here 

 is very simple. Multiply the number of the parvan by fifteen (the number
