Indian Cosmology - Reflections in Religion and Metaphysics

Published by Indira Gandhi National Centre for the Arts, New Delhi - 1995
The exact origin of astronomical studies in India is not known to us though it is fairly clear that it eventually formed part of ancient Vedic people. The earliest text on this subject now available, Vedanga Jyotisa, aims at determining the most suitable time for performing a yajna in consideration of the luni-solar-stellar situation at that time. The subject was based on so crude astronomical parameters that its failure could not escape the notice of any sky-watcher, till then it was never questioned by anybody perhaps because of its association with religious yajnas. This scheme of astronomy survived for some 2000 years.
In later India, these parameters were scraped, scope of astronomy was extended to include natural phenomena, like, eclipses, identification of planets and formulations of their motions, etc., till then astronomers often invoked metaphysics to explain cosmological facts. It occurs to us that the general people of that period in that class-ridden society was more interested in earning punyaphala through religious functions than acquiring pure knowledge. Astronomers could not or did not ignore this sentiment and so, to honour this sentiment, they found it necessary to blend religion and metaphysics with cosmology in an astronomical background. Science in ancient times had to be supplemented by speculative materials and was thus mixed up with myths and metaphysics.

Taitirya Brahmana mentions a group, Kalakajna-s, 'Knowers of time' who were conversant with calendrical science...interestingly they belonged outside the circle of Vedic people - in fact were considered as the aliens or opponents ( Tait Br. i. 1.2. 4 - 6).......it may be a possibility that these Kalajna-s were the astronomers of Harappan period.
More likely it was one of the groups that was pushed out after the battle of ten kings.
Now... Satyakam. You have to enlighten us about 'the battle of ten kings'! : )
The seminal event in Indian history, as captured in Rik Ved, post which the Vedic Indian people fractured and possibly is linked to beginning of Zoroastrianism in Iran. A rough overview (not necessarily with all details) http://en.wikipedia.org/wiki/Battle_of_the_Ten_Kings
I am sorry to say but the article posted above seems superficial and rather wrong in numerous premises. In fact instead of following up carefully on anyone topic including cosmology, this appears more a background for a vitrolic rant against Jyotish in specific and Hindu theology and faith in general. Plenty of name calling, short on facts. Who is the author? Does the author understand the concept of astronomy? Does he have any scientific training himself? (Serious question) In contrast, here is a known scientists view on the same. The author is a Prof of Applied Mathmatics Astronomy in ancient India. http://www.new.dli.ernet.in/rawdataupload/upload/insa/INSA_1/20005ac0_63.pdf The mis-statements in the above rant compared to a mathematicians view of the same can quite easily be compared.
Thanks for the critique and the link... Satyakam !
Thanks Mita Chakravorty
