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.
