1 Rohini-paksha Ayanamsa

Respected Vinay Jha ji,

Namaste,

I have copy-pasted the following message from JyotishWritings of Shri PVR ji.

It is regarding a new research aspect to take the Ayanamsa from Rohini-paksh. Shri PVR ji has

suggested the step wise procedure to select such Ayanamsa in JHora 7.62 just released.

I did try these steps with Drik Siddanta, and found some interesting results too, out of which some were

close to what I used to find with the settings of SSS.

Then I started suspecting whether these might be somewhere close to SSS or something else. Or can we

take this ayanamsa with SSS settings too, to be more accurate in predictions.

Sir, submitting for your kind expert view on this.

With regards,

Akhilesh Singh

Namaste friends,

With the sidereal zodiac, physical stars will be nearly fixed in

different areas of the zodiac, but not necessarily fixed at specific

longitudes. Each physical star (corresponding to a nakshatra) may

fluctuate around a specific longitude. But it is possible to fix ONE

specific physical star at a specific longitude and take that as the

"anchor".

* * *

The Lahiri ayanamsa is based on fixing Spica star in the middle of

Chitra nakshatra (i.e. beginning of Libra). So Chitra is the anchor.

Lahiri commission may have tried to find a bright star close to the

solar system plane near the beginning of Aries (so that they can fix

0Ar0 at its longitude) and, unable to find one, perhaps fixed 0Li0 at

Spica. But it has no philosophical or logical justification.

* * *

If you want to decide one particular Jyotish nakshatra which should be

fixed in the zodiac around a fixed physical star, in a less arbitrary

and more logical manner, Rohini fits the bill rather than Chitra.

In mythoology, all nakshatras are wives of Moon and Rohini is the

primary and favorite wife. So it is the most important nakshatra.

Moreover, Rohini is the nakshatra owned by the Creator! Also, Shiva

taught to Parvati that four nakshatras are "fixed nakshatras" and Rohini heads the list. It is the only one of

those four containing a really bright physical star. Also, Rohini is the only fixed nakshatra that also

happens lie in a fixed rasi. One more small factor is that Rohini means "the red one" and Aldebaran

(Alpha Tauri) is a really bright red star close to the middle of Rohini. In fact, Aldebaran is one of the four

brightest stars close to the solar system plane.

For all these reasons, Rohini is a far better and more logical choice

for being the anchor nakshatra.

If you want to try it, do the following in Jagannatha Hora 7.62.

(1) Select "Preferences" in main menu. Select "Related to Calculations" and "Ayanamsa".

(2) In the combo box in the ayanamsa dialog box, select "Fixed star

based CUSTOM ayanamsa". Don't add any correction in the area below the

combo box. Click "OK".

(3) In the next dialog box, about 1,000 fixed stars are displayed in the first combo box. Scroll through it

and go to "Alpha Tauri (Aldebaran)< Long 15 Ta 55, Lat -5 deg>". Please note that these stars are sorted

in the increasing order of longitude. So this entry will be towards the top of the list.

(4) In the boxes below it, enter "16" deg, "40" min and "0 sec" and

select "Taurus" in the combo box below. This will fix the physical star Alpha Tauri at 16Ta40 always!

(5) Instead of taking the oscillating Sun-earth ecliptic plane, use the *mean* solar rotation plane for a

more logically sound reference frame. For that, check the checkbox that says at the bottom "Use the

FIXED mean solar rotation plane instead of the fluctuating ecliptic plane".

Try it on a lot of charts (using drik siddhanta of course). Some

divisional charts will have changed compared to Lahiri ayanamsa, but

some may be the same to a large extent.

If only Lahiri commission used more logical thiniking, we all *might*

have been using this today instead of the standard Lahiri ayanamsa based

on Chitra!

Narasimha
