Thirty three muhūrtas (plus) two parts out of sixty-two parts (plus) thirtyfour parts out of sixty-two into sixty-seven parts, is to be known as the half-lunation (parva ) from of the Dhruvarāśi corresponding to the (sun)-constellation (yoga). Trancription : Verse 2
"icchā pavva guņão dhuvarā sio ya sohanaṁ kuņasu /
pūsāiņaṁ kamaso jahā ditthamanantaņāņihir // 2/1 Translation
The Dhruvarāśi is multiplied by whatever is the requisite ( sequential number of the parva (half-lunation ); and then from the product are subtracted (the measure of ) the constellations as pusya, etc., in sequence, according to the omniscient vision. Explanation
Let the problem be as to in which sun-constellation does the first parva ends. For this the Dhruvarāśi is
33 + ( 2/62 ) + (34/(62 x 67 ) } muhurtas. Here the Dhruvarāśi is calculated as follows:
In all there are 124 parvas, out of which 62 are bright halves and 62 dark halves in course of five-year yuga or five sun-constellation yogas. Hence, for one parva (half-lunation ) we get 5/124 sun-constellation part of a yoga. Now this is multiplied by 1830 to convert it into the type of 67 parts getting (5x 1830)/124 or 4575/62. Noting that the sun moves 1830 celestial parts in a muhūrta or moves through 1830 half-mandalas or ahorātras in a five-year yuga, we convert 4575/62 into muhurtas by multiplying it by thirty. Thus, we get ( 4575 x 30 )/62 muhurtas
3+1 2/62) + 34/162 x 67) muhüratas. This is the Dhruvarāśi required for the purpose.
Now we pose the problem for the first parva, hence the Dhruvarāśi is multiplied by one. This product is to be subtracted by the period covered by the pusya constellation. Hence we get 33+ (2/62 ) + {34/( 62 x 67 ) } - 19 + ( 45/62) + {33/ ( 62 x 67 ) } = 13+ (19/62 ) + (1/( 62 x 67 ) ).
This period remains to be covered after the sun has passed over the puşya constellation. Hence the sun remains in the āśleşā for this much period. Just after
