Problems Aplenty with respect to Uniformity in Astrology!

Astrology is a divine science. However one major drawback that it suffers is a lack of common standard and there is no uniformity when it comes to a number of factors. Listed below are some perennial problems or ever prevailing confusions with regard to astrology which don't perhaps look like getting resolved in the near future.

1) Lack of correct Ayanamsa:
Ayanamsa is defined as the angular distance between vedic first point and vernal equinox. The sidereal ecliptic of a celestial body is less than the tropical ecliptic longitude. But there was a point in time when the sidereal zodiac and tropical zodiac coincided which is taken as the starting point. Different years are taken in contention viz Lahiri (285 AD), Krishnamurthy (291 AD), Raman (397 AD), Yuktheshwar (499 AD), Vakya Siddhantha (522 AD) etc. The different Ayanamsa used results in different degrees of placements of planets causing trouble in reading horoscopes. For eg say Mercury is in 29 degrees 30 mins as per Lahiri Ayanamsa in Aries, but applying Raman Ayanamsa Mercury will end up being at 0 degrees 56 mins in Taurus.
Different Ayanamsas:
- Lahiri Chitra Paksha Ayanamsa
- Krishnamurthy Ayanamsa
- BV Raman Ayanamsa
- Yuktheshwar Ayanamsa
- Pushya Paksha Ayanamsa
- Fagan Ayanamsa
- Others (totally about 50 odd present)

2) No consensus on accurate birth time:
Sometimes natives don't have a birth time at all but even those who have it there are multiple reasons as to why it may not be correct. There are still views going on about whether birth time should be recorded as time of first breath, time of first cry, time of touching the earth, cutting of umbilical cord, time of break of placenta etc. Incorrect birth time can cause predictions to go awry.
Different Time of Births:
- Time of first breath
- Time of first cry
- Time of touching earth
- Time of cutting umbilical cord
- Time of break of placenta
- Others - time of forehead appearing, body part visible etc

3) Dasa Year Computation:
The Vimshottari Dasa system calculated based on Moon's longitude is a specific feature available in Vedic Astrology and most of the timing of events of life are matched with the running Dasa and sub periods. But there isn't a standard solution as to whether a Dasa year should be a solar year (365 point days) or a Savana Year (360 days) or based on a Lunar year (354 point days).
Different Dasa Years Used (Without decimals):
- Solar Year 365 days
- Savana Year 360 days
- Lunar Year 354 days

4) House Counting System:
Houses are of prominent importance when deciphering a chart. Which house planets are placed can give a very good insight about your course of life. But here too there are diverse views whether ascendant should start from where rasi starts which is whole sign, whether ascendant degree should be mid of first house or ascendant degree should indicate start of first house. Whole sign ascendant illustration: Ascendant Aries 29 degrees, Venus 2 degrees in Taurus and Mercury 27 degree in Aries. Venus will be counted as second house and Mercury as 1st house. Ascendant is middle of first house Illustration: Ascendant Aries 27 degrees, Venus 4 degrees Taurus and Mercury 10 degrees Aries. Here Venus will be counted as first house and Mercury as twelfth house. First house spans from 12 degree Aries to 12 degree Taurus and 27 degrees is mid point. Ascendant is start of first house Illustration: Ascendant Taurus 6 degrees, Venus 3 degrees Taurus and Mercury 1 degree Taurus. Both Venus and Mercury will be counted as 12th house. First house will roughly span from 6 degrees Taurus to 6 degrees Gemini.
Different House Systems:
- Whole sign Ascendant
- Ascendant should be middle of first house
- Ascendant should be start of first house

5) Aspects and Significator Usage:
There are some lingering confusions as to how much of aspect is really valid. Certain planets are said to have full and partial aspects. Also whether they influence a whole sign or just an extent of the house is also a point to ponder. And coming to the mysterious planets Rahu and Ketu, there are still doubts plaguing as to whether they aspect or not and even if they do tend to aspect, opinions are divided on which kind of aspects they possess. The significator or the karaka's role is also perceived differently as per various branches of astrology. For eg Mars is husband for females in one system whereas its Jupiter in another system. In some cases it is both Venus or both Jupiter.

Hence, with these kind of lurking issues prevalent in astrology it's safe to say predictions can never be cent percent accurate. There will always be a sense of vulnerability and the astrologer needs to consider a number of these factors before giving predictions. Being in the age of Kali Yuga, I doubt there will be a sure shot solution to any of the points and there are always going to be multiple views with or without logical reasoning as to which is correct. Perhaps these limitations are one reason as to why the field of occult is the way it actually is - extremely mysterious and always providing a scope for research and unraveling hidden treasures :).

Divisional Charts Ayanamsa Distance Factor - A Mathematical Mishmash!

The earlier article on Divisional Charts emphasizes on the fact that the role of time actually does not have such a big bearing when casting of varga charts as there is a sufficient time frame to play around with respect to planets actually changing signs within the zodiac. The biggest deterrent however with respect to Divisional Varga charts easily happens to be with respect to the Ayanamsa.

Ayanamsa is defined as the angular distance between vedic first point and vernal equinox. The sidereal ecliptic of a celestial body is less than the tropical ecliptic longitude. But there was a point in time when the sidereal zodiac and tropical zodiac coincided which is taken as the starting point. Different years are taken in contention viz Lahiri (285 AD), Krishnamurthy (291 AD), Raman (397 AD), Yuktheshwar (499 AD), Vakya Siddhantha (522 AD) etc. All of these happen to be roughly around 20 to 24 degrees away from the tropical zodiac. The sidereal zodiac value or the ayanamsa is deduced by deducting the relevant respective degrees from the tropical zodiac value to arrive at the ayanamsa.

In Vedic Astrology, the most popular ayanamsa in vogue happens to be the Lahiri Chitra Paksha Ayanamsa. KP astrology practitioners use an ayanamsa which is slightly off from Lahiri. Another ayanamsa endorsed by noted astrologer BV Raman happens to be the Raman Ayanamsa which is based on a computation by the great mathematician of yesteryear Bhaskara. In recent times, a new Ayanamsa has been supported by the inventor of the astrology software Jagannatha Hora based on Nakshatra Pushya being the Yoga Tara which is anchoring the zodiac and is termed as the Pushya Paksha Ayanamsa. This apart there are plenty of other Ayanamsas almost touching a half century in number.

Degree and Time Difference between Ayanamsas:
We will look at a comparison between the 4 ayanamsas listed above and see how much away they are from one another. The table listed below would tell how much is the difference in Degree Arc (Degrees-Minutes-Seconds) as well as difference in minutes duration between all these Ayanamsas.
For knowledge purposes, in order to know how these values are derived, I shall narrate it through a small illustration between Lahiri Chitra Paksha and Raman Ayanamsa.
Go to JHora astrology software and input date as Jan 1st 2019, time as 6:00 AM and place as Chennai. Select Lahiri as well as Raman Ayanamsa and note down the degrees of Lagna. Alternatively you can also scroll downwards on the natal chart details and witness a number value in Degrees-Minutes-Seconds known as Ayanamsa. The values obtained are as witnessed:

Lahiri Chitra Paksha:
Lagna : 8° 4' 51
Ayanamsa : 24° 6' 23

Raman:
Lagna : 9° 30' 39
Ayanamsa : 22° 40' 35

Subtract the Lahiri Chitra Paksha Lagna from Raman Lagna or else reduce the Raman Ayanamsa value from Lahiri Chitra Paksha Ayanamsa value and in both cases you get 1° 25' 48. Same way one can compute difference in values between any two ayanamsas.

Impact in Divisional Charts:
Now, we will see the impact or rather distortions the ayanamsas create in the Divisional Varga charts.
Listed below is a table taking into account 5 types of horoscope charts viz Rasi (D1), Navamsa (D9), Dasamsa (D10), Shashtyamsa (D60) and Nadiamsa (D150). The degree arc span for each of these are given along with the time taken to traverse in duration of minutes. (Eg. 1 degree = 60 mins and hence a Navamsa part of 3° 20' will be 3*60+20 = 200). Also mentioned are the comparisons between various Ayanamsas by pointing out the time in minutes span of which they are off from each other and also the % of change of impact that would be seen in the respective divisional charts. For eg as reckoned above taking D9 as illustration, a Navamsa pada spans 200 minutes and the difference of minutes off between Lahiri and Raman is 86 minutes meaning there would be about 43% chance (86 divided by 200) of a planet shifting to the next sign as per Raman and about 57% chance (100%-43%) that they end up within the same sign.
Explanation and Observations:
1) Rasi Chart (D1):
Taking the Rasi chart into account with the assumption that a planet may have an equal likelihood of being located in any of the degrees between 0 to 30, we figure that there is very less difference between Lahiri and KP. In 99.7% of cases both will have the planets posited in the same sign. Only in case of a planet being in 29° 55' or more in a sign in Lahiri will it end up moving to a different sign as per KP system. However comparing Lahiri with Raman, we find that there is about a 5% chance of planets being in different signs. If a planet is in 28° 34' or more in a sign in Lahiri, then it will end up moving to the next sign in Raman. Anything lesser in degrees, they would be stationed in the same zodiac sign. On the whole however, we find that the Rasi chart isn't really sensitive to the impact of ayanamsa as it is observed that there is very minute chance of planets tumbling in to different zodiac signs.

2) Navamsa (D9) and Dasamsa (D10):
It however starts getting trickier when viewing important varga charts such as D9 and D10. Between Lahiri and KP, the difference is only 3% but when comparison is between Lahiri and Raman, there seems to be a probability of close to 50% chance that the planets would involve change of signs. For instance, any planet within the range of  6° 40' to 10° in Aries sign will fall in Gemini Navamsa. If the planet is 8° 34' or more in Aries as per Lahiri, then as per Raman it'll end up being beyond 10° and end up falling in Cancer Navamsa. Thus, there is not a lot to play with and plenty of chances arise that your planetary positions won't be the same when using different ayanamsas.

3) Shashtyamsa (D60) and Nadi Amsa (D150):
Things get far more murkier and out of hand when using intricate divisionals such as D60 or D150. Here by default, the planets will fall in different signs when you take Lahiri or KP and compare it with Raman or Pushya Paksha. The difference between Lahiri and Raman in D60 amounts to a whopping 287% meaning planets will end up being 3 signs away from one other. For instance say a planet is in 1st house or sign in Lahiri, the same planet will be in 4th house or sign in Raman. When taking the minute level Nadiamsa D150, it hits ground breaking level with the difference exceeding 700%. So, in essence a planet will be 7 signs from each other, for eg say if its in 3rd zodiac sign in Lahiri, it'll end up being straight opposite in 9th zodiac sign as per Raman Ayanamsa.

Conclusion:
Thus, it is clearly visible that the playing field gets constricted with too many restrictions when involving Ayanamsa and it becomes an extremely dicey proposition. This issue cannot be bridged or resolved unless there is a uniform ayanamsa. If not, only the Rasi D1 chart would be looked at majorly and only a surface level image of D9/D10 will be used and the employment of more minute charts will end up being virtually obsolete. Those who don't however believe in Ayanamsa and are content with whatever they have been using, it is brought to light that these plaguing issues will always be inevitable and different ayanamsas will surely end up in yielding different predictions especially when more finite divisional charts are being implemented.

The Ayanamsa Puzzle!

One question where there just doesn't seem to be any unanimous answer is Ayanamsa. However for vedic astrology only the sidereal ayanamsa system seems to works best.

There are two schools of thoughts, one being Drik Ganitha Panchanga where calculations are based on Earth's rotation around the sun. The other one is Vakya Panchang based on the moon's orbit around the earth. In Vaakya Panchang or the Surya Sidhantha, calculations are not really clear and you will find significant differences in your rasi chart when compared to Drik calculations. For eg Jupiter transit always comes early (Sep 2nd 2017 to Thula in Vakya vs Sep 12th 2017 to Thula in Drik) and Saturn transit usually takes place after almost 2 months (Dec 19th 2017 to Dhanus in Vakya vs Oct 26th 2017 to Dhanus in Drik). So it's very apparent if a native were born in this period, position of planets can take a serious tumbling. There are views that Vaakya Panchang calculations are outdated and redundant but in most Nadi based systems especially thumb print astrology, only Vakya Panchang is used. Even in most ancient and Navagraha temples, they follow only Vakya Panchang and on Dec 19th 2017 millions gathered to Shaneeswara temple in Tamil Nadu to witness prayers being conducted. Though most people don't follow Vakya Panchang for astrological purpose, there is no denying that there is an esoteric as well as divine significance associated with it. Still some olden day astrologers especially in Tamil Nadu vouch for horoscopes based on Vakya and if I'm not wrong before Lahiri commission, the ayanamsa which was followed was closer to Vaakya or Surya Sidhantha.

Now coming to Drik Ganitha Panchangam. In this system there are plenty of ayanamsas which again creates plenty of distortions sometimes in Rasi chart and more so in divisional charts.

We will take 4 ayanamsas for comparison and see how each of them gives different results and if you are doubtful about birth time, it may need to be tweaked based on the ayanamsa you choose.

The Ayanamsas under consideration are:
1) Lahiri Chitra Paksha Ayanamsa
2) KP Ayanamsa
3) BV Raman Ayanamsa
4) Pushya Paksha Ayanamsa

The first two are close and there is not much difference and similarly the latter two are also somewhat closely related. Apart from these there is also the center of galactic ayanamsa which is said to be 28 minutes off from Lahiri and Yukteshwar ayanamsa very close to Raman.

Average time in which Lagna is in a sign is 2 hours = 120 minutes. Dividing 120 mins by 30 degrees, we get 1 degree = 4 minutes. A part of Navamsa is 3 degrees 20 mins which makes it around 13.33 mins in a particular sign (can say within approx 13-14 mins Navamsa changes in a sign)

You need to know these parameters to find out various approximations.
Lahiri Chitra Paksha Ayanamsa : 0:00 (Base Point)
KP Ayanamsa : 0:05 off
Pushya Paksha Ayanamsa: 1:07 off
BV Raman Ayanamsa: 1:26 off

Lets take the date 21st Apr 2018 with place being Chennai. At 11:35 AM, Lagna enters Cancer. As per KP it would have entered about 20 seconds earlier. As per PP ayanamsa, it enters almost 4 and half minutes earlier (1 degree is 4 mins and 0.07 constitutes around 30 seconds. We say 1 degree = 0.60 =4min, thus 0.30=2min, 0.15=1min, 0.07= about half a minute). So in this case even before 11:31, Lagna is already in Cancer. If we take BV Raman, its almost 6 mins away from Lahiri in terms of Lagna. So at just past 11:29 it already has gone into Cancer. In my opinion 6 mins is a substantial amount of time and if you see someone having 29 degrees in Lagna as per Lahiri, then for sure the person has already moved into the next sign as per BV Raman. Thus the correct Ayanamsa is absolutely essential when fixing the birth time and it cannot be the same across different systems.

Similarly you would find significant differences in Moon where there are bright chances that you may actually be a pada forward as per Raman in comparison to Lahiri and difference of Dasa balance can be upwards of 2 years.

Personally, despite Raman Ayanamsa being way off, I find that for timing of events as per Vimshotari Dasa it tends to work very well. Lahiri is however the most popular but it was more used as a tool to fix a umbrella consensus because various calendars were being used and in order to create uniformity with the base being Chitra, the brightest star in the constellation.

I would like to know which ayanamsa is most correct? Also does it makes sense to use ayanamsa as per your choice based on how it suits your events? Which was the one followed by the great Sages?

Listing below a summary of the different ayanamsas used for casting a horoscope.

A) Vakya Panchang :
1) Vakya Panchanga based horoscope
2) Surya Sidhantha based on beeja correction

B ) Drik Ganitha Panchang :
- Closer to Lahiri
1) Lahiri Chitra Paksha Ayanamsa (base 0)
2) KP Ayanamsa (5 mins off Lahiri)
3) Center of Galactic Ayanamsa (27-28 mins off Lahiri)

- Far off from Lahiri
4) Pushya Paksha Ayanamsa (1degree 7 mins off Lahiri)
5) Yukteshwar Ayanamsa (1 degree 21 mins off Lahiri)
6) BV Raman Ayanamsa (1 degree 26 mins off Lahiri)
