Ayanamsa Issue - Views of

Chandra Hari




Article By Sreenadh



Chandra-Hari is an Indian Astrologer (job: ONGC Engineer),

and is a true researcher on the ancient Indian astrology and

astronomy. This article tries to present the core ideas of Hari in a

comprehensible way.

He has written 3 books on Ayanamsa. 1) A small book in

English with the name "True Ayanamsa" published around 1994 when the

idea originated. 2) A Book named "Rasichakram" in Malayalam

published in 1996. 3) A very big book named "Hindu Zodiac and Ancient

Astronomy" in English published around 2003 (Sri Sabarigiri

Publications, Kadapra PO, Kumbanadu, Pin-689547 Price: Rs.600/-)

In book named Rasichakram he postulates: Zero Ayanamsa year -

AD.238; Ayanamsa - 46 min more than Lahari. But in his book "Hindu

Zodiac and Ancient Astronomy" he modifies his arguments and

postulates: Zero Ayanamsa year - AD.231; Ayanamsa - 44 min more than


This article presents the views of Chandra-Hari as given in

his book Rasi-Chakram. I have tried my level best to compile his

ideas in a systematic manner, keeping the continuity of the

mathematical concept and the thought process involved. The

mathematical portion of the ideas introduced by Chandra-Hari about

the ayanamsa inherent in Surya-sidhantha and his ideas about the Rasi-

chakra division is depicted. In his book (named Rasi-Chakram) Hari

proposes that Zero Ayanamsa Year is AD.238 and that his ayanamsa is

more than that of Lahari by 46 min. Let us try to understand how he

arrived at these results.


Analysis of Hari's Rationales



Basic Rationale 1:


The zodiac originated mathematically, considering the

revolution of the nodal points Rahu and Sikhi. Thus Ra-Si chakra is

an abbreviation for Rahu-Sikhi Chakra. The rotation of these nodes is

in rhythm with the movement of equinox, if we consider the duration

required for precession of 360 deg.


[i.e. 25785 years means 1385 nirayana revolutions of Rahu-Sikhi. i.e.

Nirayana revolution period of Rahu = 6792.977 days]

Theoretically, or by intuition, he gives the following maths: -

Rate of precession (of equinox) per year = 360 deg/25758 = 120

deg/8556=50.31446541 sec

He says that, this (the importance of these numbers) can also

be proved, considering the modern values of Nirayana and Sayana

years. For example:

Nirayana Year = 365.2563625 (Modern value)

Sayana Year = 365.24219 (Modern value)

The difference between 8586 sayana days and 8586 nirayana


= -121.684 days

i.e. precession of equinox in 8586 years = 119 deg 56 min =

120 deg

[This also indicates that the year length used in old-suryasidhantha

is little different. The year-length considered in old-suryasidhantha

is 365.25875 days. The "why" of it would be explained in Rationale 4]

Using the above method we can also prove that 25758 nirayana

years is equal to 25759 sayana years.


Basic Rationale 2:


The importance of yuga numbers is that they are precession

seconds (in precession circle).


Kali-yuga = 432,000 sec = 120 x 3600 sec = 120 deg = 8586


This holds good if and only if, this period contains the

complete revolutions of the 7 planets and the nodes (Rahu-Sikhi). To

prove it he gives the following table. The importance of the number

8586 is emphasized.

Thus we see that, yuga numbers could actually mean precession

seconds. Therefore, now we could say,

Kali-yuga = 432,000 sec = 120 x 3600 sec = 120 deg = 8586


Dwapara-yuga = 864,000 sec = 240 deg precession = 17172 years

Tretha-yuga = 1,296,000 sec = 360 deg precession = 25758


Kritha-yuga = 1,728,000 sec = 480 deg Deg precession =

34344 years

Maha-yuga = 4,320,000 sec = 1200 deg precession = 85860

nirayana years

Manuvanthara = 86400 deg precession

Kalpa = 3360 deg precession


According to Vedic astrology the Kalpa began on a new-moon

day/Sunday/first day of Aris (mesha)/and the planetary longitudes

(sputa) of all the planets were zero. Thus, theoretically all this

means that, each yuga-pada (8586 years) starts and ends in a new-moon

day, and that at the start and end of each yuga-pada a solar eclipse

occurs. (It is a pre-supposition put forward by old-Suryasidhantha

and the above maths. It must be theoretical reasoning followed by old-

Suryasidhantha) But it actually does not happen. The "why" of it

would become clear when we see rational 4)


Basic Rationale 3:


Kali-yugadi Ayanamsa is 46 deg 40 sec.


[He depends on the story that the birth of Brahma was in Rohini

Nakshathra. Rohini was also praised as Prajapathi, i.e. Brahma, in


i.e. Vernal equinox at the beginning of Kali-yugadi = 46 deg 40 sec

Therefore, Zero Ayanamsa years (elapsed) = 46 deg 40 sec x (8586/120

deg) = 3339

Here a striking similarity attracts our attention. 3339 is an

Rig-vedic number. Rig-veda (3.9.9) says of "3339 devas who worship

Agni". If Agni really means vernal equinox, then this could

mean, "the vernal equinox is 3339 years away from zero point".

i.e. After 3339 kali years the sayana and nirayana zodiacs

super conjuncts. Whether depend on the above maths or on the Rig-

vedic statement, we arrive at the same conclusion.

Kali Yuga (Beginning) + 3339 = Zero Ayanamsa Year

3102 BC = - 3101 AD

i.e. - 3101 AD + 3339 = AD. 238

i.e. Zero Ayanamsa Year = AD.238.

Thus the definite formula for determining the ayanamsa of any year

would be: -

Ayanamsa for the year (Y) = (Y-238) x (120 deg/8586)


= (Y-238)/71.55


Here another striking similarity attracts our attention. The

Number of human heartbeat per minute is 71 or 72. It might be

possible that 71.55 is the actual value of the heartbeat for a

person. If so, we could also prove that the rhythm of the universe

and the biological clock in humans are mutually related. The

biological clock, circadian rhythm etc comes into consideration.

Example for calculating ayanamsa for any year: -

Hari Ayanamsa (1995) = (1995 - 238)/71.55 = 24.55625437

= 24 deg 33 min 22. 52 sec

Lahari (Chithra-paksha) Ayanamsa of 1995 = 23 deg 47 min 30


Difference = Hari Ayanamsa - Lahari Ayanamsa = 46 min

i.e. Hari Ayanamsa is 46 min more than that of Lahari. In other words

if we subtract 46 min from the sputa (Celestial Longitude) arrived at

by using Lahari ephemeris, we would get sputa based on Hari Ayanamsa.

Hari does not stops here - he goes on to prove how the zodiac

was divided into Rasis (Signs) and Nakshathras (Stars), based on the

fiducial star Moola (240 Deg), 108 div of Nakshathras (3 deg 20 min

each), and the above said actual position of vernal equinox at Kali-

yugadi (46 deg 40 min). For this, two new ideas are introduced, and

he dives deep into old-suryasidhantha to prove them.


Basic Rationale 4:


(i) Zodiac is considered and presented as a mathematical

model in old-suryasidhantha, trying to comprehend the perfect rhythm

of the universe.

(ii) Even though the creator of Surya-sidhantha (i.e. Mayan),

knew about the actual vernal equinox at Kali-yugadi (i.e. 46 deg 40

min), Kali-yugadi-Ayanamsa was considered as 60 deg (in old-

Suryasidhantha), for the perfection of this mathematical model.


According to the precession considered in old-suryasidhantha: -

Precessional Cycle = 21600 years (instead of 25758 years)

If we relate this to yuga years -

432000 (Kali-yuga) = 21600 x 20

4,320,000 (Maha-yuga) = 21600 x 200

Maha-yuga = 200 x 360 deg = 72000 years

120 deg precession = 4320000/600 = 7200 years (instead of

8586 Years)

If we divide the number of revolution of planets in a

mahayuga with 600, we could get the number of revolutions of planets

per 7200 years. Thus we get -

Sun = 4,320,000/ 600 = 7200.00

Mars = 296824/600 = 3828.04

Jupiter = 364200/600 = 607.033

Venus = 7022388/600 = 11703.98

Mercury = 17937000/600 = 29895.00

Rahu = 232226/600 = 387.0433

Here the results are very near to whole numbers. That means

in 7200 years the mean values for planets complete, whole number of

revolutions. If we consider little bigger period, for example take,

7200 x 25 = 4320000/24 = 180000 years, we could prove that it contain

whole number of revolutions.

[The above mentioned proof, is not given in Hari's book named Rasi-

chakram. But I think anybody could verify it, as the logic is

straightforward. About not giving the number of complete revolution

for Moon and Satern in mahayuga also Hari gives some reasons, which I

could not grasp]

"As according to old-suryasidhantha, all the revolution

numbers of planets are whole numbers and multiples of 24, this means

that, in 180000 years, the mean positions of planets conjuncts at

zero-point. This is a concept fundamental of vedic astronomy. Surya-

sidhantha relates the imaginary mean positions of planets at the

start of yuga with the actual planetary positions that will occur

after 3600 years".

As Surya-sidhantha takes 4320000 as Maha-yuga the

Precessional Cycle (i.e. for 360 deg) becomes 21600 years. Thus it

necessitates 60 deg precession for Kali-yuga. If you compare with the

actual data, you may feel that it is an error. But in reality it is

precious mathematical model. The Precessional Cycle is a Mathematical

model put forward by the creator of Surya-sidhantha. What was the

need of such a model? It was to relate the yugadi mesha-sankranthi

with the new moon day that all these mathematical exercise was done.

[Or, was it to incorporate the number 216000 (i.e.360 x 60)? The

importance of this number is that: Prana (one human breath) means 4

seconds. According to yoga and upanishads one day of a human body

means 21600 prana = 360 deg x 60 = 21600 min of zodiac] For this, the

mesha-sankranthi at the beginning of yuga, was considered to happen,

9 days and 37 nadis before (9 deg 37 min). For that only nirayana

year with length 365.25875 was chosen. It was not because that he

doesn't know the actual nirayana year length. The actual precession

according to Surya sidhantha was 50 sec.

[How can we know that the year length used in Surya-sidhantha is

365.25875 days? According to Old-Suryasidhantha -

The Average Number of days in a Maha-Yuga = 1577917800 days

One Maha-yuga means = 4,320,000 years

Therefore Year-Length = 1577917800/4320000 = 365.25875 days

[Really I couldn't figure out how he got that "the actual precession

considered by Surya-sidhantha is 50 sec". There might be a sufficient

reason. But I don't know what it is.]

All this means that first stellar division (first star) is

Jyeshta that falls between the line joining the hypothetical Equinox

line of old-Suryasidhantha (the line joining 60 deg Vernal equinox

and 240 deg fiducial star Moola) and the line joining the actual

Equinox line at Yugadi (line joining 46 deg 40 min and 226 deg 40

min). The first rasi division is (sign - Cancer) falls between the

line joining the hypothetical Sayana Rahu-Sikhi (line joining 300 deg

Sayana-Sikhi/planetary conjunction point and 120 deg Sayana Rahu) and

the hypothetical Ecliptic (line joining 330 deg and 150 deg) of Old-

Suryasidhantha. Thus forms the Zodiac with stars 13 deg 20 min each

and Signs with 30 deg each.


Why Hari Jumped to Thanthra and Proposes that Zodiac is Thanthric?


When the thoughts of Chandra-Hari traveled up to this, and

bombarded with the concepts such as Moola and Rhythm of the universe

(music of the stars or biological clock - what ever you name it),

some other striking similarities came to his mind. Some examples

would be: -

(i) Moola is the base of zodiac division - Mooladhara is the base

point from where yoga starts.

(ii) Horoscope is also called Kundalini - In yoga also Kundalini

(serpent power) is important.

(iii) Rahu-Sikhi (Serpents - Kalasarpa) is the underlying factor of

Rasichakra - Kundalini in yoga is also symbolized as serpent.

(iv) Kalapurusha is a concept in astrology - Sankhya and Yoga also

speak about purusha.

(v) The universe is Rhythmic - The human body is also in rhythm

with universe. [This needs further clarification. Prana means 4

seconds. According to yoga and upanishads one day of a human body

means 21600 prana. 360 deg x 60 = 21600 min of zodiac. Also consider

the above said importance of the number 71.55]

All these similarities prompt him to dive deep into concepts

such as Tanthra/Yoga and Circadian-rhythm/Biological-clock etc.

Let Hari's concepts be right or wrong - shouldn't we

appreciate his efforts?



In the view of Chandra-Hari: -

(i) The yuga concept is nothing but a deep-seated theory on

ayanamsa. That is why it was given this much importance by Old-Surya-

sidhantha (By Mayan, Included in Pancha-sidhantika by Varaha-Mihira),

New-Surya-sidhantha (By Aryabhatta I), the Epics and Puranas.

(ii) Rasi-chakram (Zodiac) is a mathematical model, put forward by

Rishis, which postulates the existence of a Sidereal (Nirayana) Zero-

point (Meshadi or Aswinyadi), as well as the conjunction of 8 planets

at this zero-point in the beginning of every yuga.

(iii) The Sayana-Nirayana division is deep seated in Hindu

mythology and the Vedas gives ample proof of this. Both the Sayana

and Nirayana systems existed in Vedic period. (Mayan the creator of

Surya-sidhantha was only a genius compiler of the then prevailing


At the end, let me mention one more point as well (taken form

the book Rasichakram). In the first hymn of purusha-suktha,

i.e., "sahasra seersha purusha sahasraksha sahasra path, sa bboomim

viswatho vrithva adhyadhishtath desangulam", a man with 1000 heads

and 1000 eyes and 1000 legs is mentioned. But really, as everybody

knows, 1000 heads needs 2000 eyes and 2000 legs. i.e., the meaning of

the word Sahasra = 1000, does not fit well. (We may escape the

confusion by saying that Sahasra means `many'). But based on

sathapatha brahmana, KR Krishnamoorthi says that, Sahasra

means `Great circle that divides a glob into two equal parts'. This

is note worthy. Then suddenly we become aware that many astronomical

terms are used in the hymn. The following picture clarifies this

point. Now we could see that:-

Seersha Circle (Sahasra seersha purusha) = Prime meridian

Aksha Circle (Sahasraksha) = Celestrial Equator (also known

as Nakshathra vritha in sanskrit)

Patha Circle (Sahasrapath) = Nodal Circle (also known as

Vikshepa vritha in sanskrit)

Bhoomi Circle (Sa-Bhoomim) = Horizon (also known as Harijem

in sanskrit)

Viswa Circle (Viswatho vrithva) = Ecliptic (also known as

Apamandala vritha in sanskrit)

Now, if this interpretation by Hari is right, we gets ample

proof for the fact that, Vedic Knowledge is really amazing.


Note: - Hari is a genuine genius, who argues vigorously about the

concepts he believes in, and his language is rude. (Those who read-

his-book / speak-with-him, can understand my point) His ideas are

stunning and capture our attention. We should admit his true

dedication towards astrological research. We are all searching for

the truth of astrology, and are trying to be sincere as much as

possible. I am not trying to become an advocate of Chandra-Hari.

While predicting using the Vimsothari desa system, I also feel (As

Guru Sanjay Datt pointed out) that, at times Lahari-Ayanamsa is

better than Chandra-Hari's to arrive at correct results. But still, I

feel passionate towards his mathematical concepts, and somewhere

there in the path, the truth and the trustworthiness of the true

ayanamsa hides.

But be at your own risk!! Beware of what I said about his language.

> ======================================


Thank you for your interesting post regarding the true ayanamsa. I

found it especially interesting in comparing the Hari ayanamsa to the

Fagan/Bradley ayanamsa used by western sidereal astrologers. To wit:


Hari Ayanamsa (1995) = (1995 - 238)/71.55 = 24.55625437

= 24 deg 33 min 22. 52 sec

Lahari (Chithra-paksha) Ayanamsa of 1995

= 23 deg 47 min 30 01 sec

Fagan/Bradley Ayanamsa of 1995-01-01

= 24 deg 40 min 26.44 sec


Difference = Hari Ayanamsa - Lahari Ayanamsa = 46 min

Difference = Hari Ayanamsa - Fagan Ayanamsa = 7 min


Only a 7 minute difference between the two. No other ayanamsa I'm

familiar with comes as close to matching Fagan/Bradley which was

derived using totally different methods.


Thanks again for the post.
