For individuals, the moment when Sun arrives at same sidereal longitude as at the time of birth is known as Varsh-pravesh, and horoscope made at this juncture is effective for one whole year for that individual. Adding one rāshi to birthtime value of sidereal Sun will give successive mās-pravesh kundalis each effective for a month. Popular methods of preparing
varshapravesha kundalis are crude variants of this ancient siddhāntic method.
National and international horoscopes are made on the bases of similar principles but along different guidelines. Solar transit into sidereal (Nirayana) Mesha (Aries), ie., Sun at sidereal FPA (Firsr Point of Aries or sidereal Zero Sun) is known as solar or Varshārambha (beginning of Hindu year). For religious purposes, beginning of bright half (Shuklādi) of the lunar month of Chaitra is Varshārambha (whose horoscope is popularly known as Varsh-kundali), but for astrological purposes Sun at sidereal FPA is Varshārambha. Horoscope (kundali) made at this juncture, known as
Jagat-lagna, is effective for one whole year.
Every panchānga (religious almanac) publishes
Jagat-lagna on its cover page, alongwith Varsh-kundali. Varsh-kundali is less effective, while Jagat-lagna is the dominant kundali for the whole year. If the lagna-rāshi in Jagat-lagna is Chara, other three thri-monthly kundalis also become important, but if Jagat-lagna's lagna-rāshi is Sthira, then Jagat-lagna is all powerful.
There is no dispute among panchāngas about above points. But almost every panchānga makes the Jagat-lagna from the place of its publication. As a result, there are as many Jagat-lagnas for the world as there are number of panchāngas. It is not difficult to guess that these kundalis made from diverse locations must differ from each other. There is no consensus among panchānga makers about the place from which Jagat-lagna should be made.
Ancient authorities believed
Mt Meru to be such a centre. It was believed to be centre of all universes. Mahabhārata clearly states that all planets revolve round it. Even Buddhist and Jain literature is replete with eulogies of Mt Meru. If Mt Meru is imagined to be Pole and annual horoscope is drawn there, meruvian latitudes will describe twelve bhāvas upon the globe. During Kaliyuga, people forgot this ancient method of drawing world's Jagat-lagna and Mt Meru came to be identified with geographical North Pole, which is against geographical facts. Suryasidhhānta and Narpatijayachatyā explicitly mention that Mt Meru lies at the middle of the Earth in the land of Jamboonada in Jamboodveepa. Jamboonada, Jamboodveepa and a mountain like Mt Meru must lie at the surface of Earth, but Reverend Burgess wrongly translated Suryasiddhāntic term
as at the centre of earth-globe, instead of as 'bhoomadhya-rekhā' , ie, at equator.
The highest mountain at equator in Africa, where Jamboonadi ( >Jambunazi >Jambenazi >Jambezi) flows, is Mt Kenya, where an administrative headquarter and important town of Kenya lies, known as Meru. This Mt Kenya is the Mt Meru of ancients. Jagat-lagna drawn from here is effective for the whole world.
Data about rainfall, earthquakes, tsunamis, floods, major wars, etc have been checked for hundreds of years and found to be true for the world, but only when Suryasiddhāntic Ganita (mathematics) is followed. Scholars attached to KSD Sanskrit University and scholars working in many other institutions of India undertook extensive researches on these topics which have yielded positive results, and recently four major research projects related to
Medini Jyotisha (terrestrial astrology) have been approved to widen the scope of research.
Astrological Nodes of the World :
Net result of these researches is that world's horoscope (Jagat-lagna) ought to be made from Mt Meru (Mt Kenya) according to Suryasiddhāntic mathematics. Another important finding is that India's national horoscope should be made from
Vidishā. Like Vidishā, there may be other nodal centres for making regional horoscopes for other major regions of the world, but we have no clue about these regional nodes. Some western scholars are also trying to find out these forgotten national nodes.
Some important international and national horoscopes may be discussed under separate topics in order to elucidate the mechanism of making such horoscopes. One such example is the '
Horoscope of Kaliyuga (Kali Age)', a topic in the Vedic Astrology' section.
