Sarasvati is ground-truth. So is Mahabharata an account of the ancient history of Bharat. The dating of this epic is fundamental in establishing the historical chronology of ancient Bharatiya Itihaas.
Veda Vyasa who wrote the Mahabharata observed the sky inscriptions from the banks of River Sarasvati. The epic describes a pilgrimage of Balarama (elder brother of Krishna) from Dwaraka-Somnath(Prabhas Patan) to Mathura along the banks of River Sarasvati in 200 shlokas in the S'alya Parvan.
This date of Mahabharata War is crucial in determing the chronologies in the ancient history of Bharat since many epigraphs and inscriptions with a historical import, refer to time-reckoning based on the starting date of Kaliyuga which is close to the date of the Mahabharata War.
Dating Mahabharata events using astronomical references
Using a set of modern technology tools such as Planetarium Software (Sky Map Pro 5, Red Shift), Panchanga Software compiled by a Japanese professor to produce the equivalence between Kaliyuga dates and dates of the Christian era, Dr. Narahari Achar has tried to authenticate the accuracy of observations made by Veda Vyasa in the Mahabharata.
In the epic, Veda Vyasa himself says that day in and day out he is watching the planetary positions on the skies. His recording of over 70 such planetary events are almost like a record of celestial inscriptions within the text. These celestial events are used to date the events which occurred on the banks of River Sarasvati -- events which are described in the epic poem. Since the planets on the sky and the celestial events are remarkably accurate and follow a precise pattern of cyclical movements, to a rhythm of time, the determination of planetary positions as observed by Veda Vyasa will help determine the date of events described in detail in the shlokas of Mahabharata.
In the past, many scholars have attempted to arrive at the date of the war based on one or two celestial events mentioned in the text. But, the contribution made by Dr. Narahari Achar is unique in that he tries to find a series of dates which is consistent with almost ALL the 150 plus astronomical references contained in the text.
Akhila Bharateeya Itihaasa Sankalana Yojana has published a reference work by Shriram Sathe as a compendium of astronomical references in the Mahabharata. This work has provided the basis for this International Colloquium.
In a paper presented at the international colloquium held in Bangalore on Jan. 5 and 6, 2003 and organized by Akhila Bharatiya Itihasa Sankalana Yojana, Mythic Society and Indira Gandhi National Centre for Arts Southern Chapter, Dr. Achar conclusively proves that the observed celestial events on the sky, observed by Veda Vyasa were based on a variety of observations:
1. Lunar-solar-lunar eclipse sequence occurring within a period of one month and one lunar-solar eclipse sequence occurring within just 13 tithi-s;
2. A comet (Haley's comet) is observed on the sky;
3. Bhishma waits for the uttarayana punya kaala (winter solstice) and ashtami tithi to arrive before his soul departs from the mortal body;
4. Karna describes to Krishna the observation of unusual planetary conjunctions -- almost all the seven planets coming together;
5. Balarama's pilgrimage starts on a particular tithi and nakshatra and ends after 42 days on a particular tithi and nakshatra. All such observations are found by Dr. Narahari Achar to be consistent with only one date: about 3000 BCE, i.e. about 5000 years ago. No other date matches so consistenly with all the astronomical observations or, what may be called, celestial inscriptions.
This finding is historic and constitutes a watershed in our understanding of chronology in ancient itihasa of Bharat.
Firstly, it establishes the historic authenticity of Mahabharata as a sheet anchor of Bharatiya Itihas.
Secondly, Veda Vyasa should have recorded only observed celestial events when he provides precise astronomical details in the text. The observations should have been made from the banks of River Sarasvati close to Kurukshetra. Dr. Narahari Achar reconstructs the skies as seen by Veda Vyasa from this location close to Kurukshetra.
Thirdly, together with the scientific discovery of the River Sarasvati in north-west Bharat as ground-truth and not a myth, it is possible to state with authenticity that the modern history of Bharat begins with the historic document, the Mahabharata and the War which occurred on the banks of River Sarasvati.
Fourthly, Balarama's pilgrimage along the banks of River Sarasvati as described in 200 shlokas of Salya Parva of the Mahabharata was a historic event and provides a geographical account of northern Bharat.
Fifthly, the history of modern Bharat begins from about 3000 BCE, that is, from the Kaliyuga which is reckoned from this date, according to Bharatiya Kala Ganana.
Sixthly, there is no historic document in human history which records historical events with such astonishing accuracy, to the last tithi and nakshatra.
Seventhly, this demonstrates the remarkable astronomical knowledge possessed by the rishis of Bharata, exemplified by Veda Vyasa as early as 5000 years ago and establishes Jyotisha which was evolved in Bharata, as an early astronomical scientific discipline.
Thus, using modern astronomy computer-based software tools, it is now possible to state that Mahabharata of Veda Vyasa is the earliest recorded history of Bharat and the modern history spans from over 5000 years of continuous, indigenous civilization. The chronology of Bharatiya Itihas should be reconstructed from this date and based on this historical document, and need not be based on foreign travellers' accounts or theories propounded by western indologists.
The following key dates are found to be consistent with the sky inscriptions observed by Veda Vyasa:
Krishna's departure on Revati Sept. 26, 3067 BCE
Krishna's arrival in Hastinapura on Bharani Sept. 28, 3067 BCE
Solar eclipse on Jyeshtha amavasya Oct. 14, 3067 BCE
Krittika full moon (lunar eclipse) September 29, 3067 BCE
War starts on November 22, 3067 BCE (Saturn in Rohini, Jupiter in Revati)
Winter solstice, January 13, 3066 BCE
Bhishma's expiry, January 17, 3066 BCE Magha shukla ashtami
A fierce comet at Pushya October 3067 BCE
Balarama sets off on pilgrimage on Sarasvati on Pushya day Nov. 1, 3067 BCE
Balarama returns from pilgrimage on Sravana day Dec. 12, 3067 BCE
On the day Ghatotkaca was killed moon rose at 2 a.m., Dec. 8, 3067 BCE
These dates, in particular the occurrence of Winter solstice which is a critical celestial event, gets corroborated by the chronology of Kaus'i_taki Brahmana which should not be far-removed from the date of S'atapatha Brahman.a which has been established by Dr. BN Narahari Achar based on the Brahmana observations that the Kritthika (Pleiades group) rose exactly at the east point (eta_ ha vai pra_cyai dis'e na cyavante: S'Br. II Kanda, Ch. 1, Br. 2,3).
In Kaus'i_taki Brahmana there are two statements:
sa vai ma_ghasya_ma_vasya_ya_mupas'asatyadangabha_vai sannupeme (KBr. XIX,3)
mukham va_ etat samvatr.sarasva yatr. pha_lguni_ paurn.ama_si_ mukhamuttare puccham pu_rve (KBr., V,1))
[cf. S'Br. VI.2.2.18; Taittiriya Br. 1.1.2.8].
These observations indicate that
the sun reached the winter solstice at the full moon Ma_gha
the year was considered to be at its end at the full-moon at the star group Purva Phalguni_.
