Nishek lagna calculations:

Vedic astrology is astrology of par excellence, it provides means of judging the experiences of the soul in the mother’s womb itself.
It is calculated based on angular distance in degrees,minutes and seconds between planet Saturn/shani and Gulik( What is a Gulik) plus the bhava Madhya( middle of house or cusp of lagna) and the 9th house(bhava) mid .
Then convert the above number in to signs or rashis( 12 x 30 degrees = 360 degrees). If the above sum is in the invisible visible half of the horoscope( 7 to 12th house), add the degree of moon( Chandra) within a sign /rashi to the above product, else not.
This would give you the longitude of nishek lagna.
Interpretations based on Nishek Lagna
Based on niskek lagna/ascendant- the good and bad experiences by the person in the womb can be found out based on Vedic astrology principles. That includes longevity of parents etc.
Like benefics in or aspecting 9th house of father and 4th house of mother or karakas of father and mother respectively( sun and moon) could mean longevity and good health to parents and in case of malefic it could be otherwise.
The mental state on the womb could be judged based on lord of 4th and 5th house respectively.

Now Locate the Nishek lagna for sri narendra Modi ji
What is the Nishek lagna of sri narendra modi ji ?
Let us Locate the Gulik
add to this 133 deg 20 minutes for Gulik makes it 133+150 + ( 35+20) minutes = 283 deg 55 minutes = 30×9 + 13 deg and 55 minutes = Capricorn sign (maker rashi) with 13 degrees and 55 minutes.
Also adding 1 degree 9 minutes simple add it to 14 degrees 55 minutes maker Rashi
9th bhava Madhya is cancer around 1 degree 9 minutes.
That’s around 90 degrees + 1 degree 9 minutes
= 91 degrees 9 minutes
= 30×3 degrees + 9 minutes
So Total = (9+3)x 30 + 13 degrees + 55 minutes + 9 minutes + 1 degrees + 9 minutes
So total = 12x 30 + 14 degrees + 68 minutes = 12×30+ 15 degrees + 8 minutes = Aries sign or mesha rashi with 15 degrees and 8 minutes.
Now subtract longitude of Saturn or shani from the Gulik’s longitude(149 degrees 39 minutes= is in Leo 29 deg 39 minutes
1 sign 15 deg 8 ‘ – 5 sign – 29 degree -39 minutes
= -4 sign -14 deg -31 minutes
= -120 dgeree – 14 degrees -31 minutes = -134 degrees – 31 minutes- is around 15 degrees scorpio = Nishek lagan of sri narendra modi ji.
so Scorpio or Vrishchika rashi or Leo sign is the lord of sri Narendra modi ji’s nishek lagna or ascendant. It is the same as the current ascendant

As Saturn is also ayushkaraka so overall gives great longevity to the mother. Yes, placement in 7th bhava may give some health issues.
That is mercury planet(Budha) or Virgo sign(Kanya Rashi) ruling the 11th house.
That is sitting in the own sign Virgo or Kanya Rashi along with Ketu. so significantly enhances the longevity of his respected mother hiraba.
