calculation of mandi in jhora-correct?

[Guest guest]

everyone of us know that mandi position is very important in the chart.Escpecially astrologers in Kerala give a lot of importance to mandi.Most importance use of mandi is in fact verification of birth time in natal charts.

 

formula

 

 

"mandi sphhuta* 81/27 should be janma nakshatra or its 9th or 18th.Otherwise birth time has to be corrected."

 

The method to find Mandi longitude is given in the famous Prasna Marga and other classical jyotish texts.

 

 

I am reproducing the text from Prasna Marga

 

From Sunday onwards during daytime the position of Mandi will correspond to the rising

degree at the end of 26, 22, 18, 14, 10, 6 and 2 ghatikas after sunrise ; provided the sunrise is at 6

a.m. If the length of the day is more or less than 30, these figures have to be appropriately

changed. Thus for example if the length of the day is 32 ghatis on a Sunday, the sunrise being at

5-40 a.m. then Mandi's position will correspond to the rising degree at the end of 27.73 ghatis

after sunrise.

During night times, the position of Mandi will correspond to the rising degree at the end

of 10, 6, 2, 26, 22, 18 and 14 ghatis respectively from sunset from Sunday onwards. These

figures hold good provided the duration of night is 30 ghatis. Appropriate alterations should be

made if the nocturnal duration is more or less than 30 ghatis. If for instance on a Saturday, the

duration of night is 34 ghatis then the position of Mandi corresponds to the rising degree at 15.86

ghatis after sunset

 

 

Jhora and Mandi

 

Jhora has prederences where we can chose Mandi to be rising at either beginning/middle and end of saturn position.

 

The mandi longitude obtained by hand calculation differes by a large degree say(3 to 4 degrees) when we chose "Mandi rises at the end of saturn position".But this is the closest option.

 

If we choose other two options " beginning.middle".the longitude obtained is far off from which obtained via manual calculation.

 

 

To check this one can calculate rise of mandi at any day -even today and you will find there is difference
