An absolute delight and an honour to have had the opportunity to spend time with Prof. R. N. Iyengar over the last few days.

Beyond the immediate impact of his original discovery and scholarship on both Indian and global chronologies — which is itself staggering when one comes to think of it — his book Mahāsalilam is, in my humble opinion, one model for what the future (technical) output of any Indology enterprise that aspires to produce scholarship of enduring value should look like: work that lasts far beyond events.

Thank you, Prof. Iyengar, for your truly historic contribution. At 83, your energy, wit, and lucidity — along with your mastery of sources — are an inspiration!

Dear Megh, I am humbled by your kind words. 

It was a pleasure for me to have participated in the "Book Discussion" on  Mahāsalilam that belongs to all of us. 

Somehow, I had the good fortune to have come across the manuscripts. You did an excellent job in offering your own discussion points and equally so in bringing on to the stage Prof.MD Srinivas for a

scholarly Q&A. Even though Prof. Sriram could not be in person, his written comments read by you and shared with me, are keeping me occupied. The planetary models of VGJ, as developments over the Mahāsalilam by the School of Vrddha-Garga are yet to be published. The learned audience at the CPRI Inst. of Indology was clearly interested in the subject. The questions were all searching and indicated a welcome effort to compare and contrast the present day Jyotisha (astrology) with the most ancient observations and related concepts. Let me thank Dr. Nandita Krishna for the invitation and you - for convincing me to travel to Chennai, literally taking care of me platform to platform.

🙏

The pleasure was all mine, and it truly was a privilege to have this opportunity to learn.

I can’t recall when I last saw anyone hand-write six pages — that too with a fountain pen — as Prof. M. S. Sriram had done, and then email them.

Prof. M. D. Srinivas very kindly agreed to be part of, and elevate, the proceedings.

Dr Nanditha Krishna must indeed be thanked for being a very gracious host despite a personal emergency. 

An audience that arrived before time, stayed till the end, and purchased all copies that were for sale, sent across by folks at CSU, courtesy of Hon’ble VC Prof. Shrinivas ji. 

Best, 

Megh

Dear Megh,

Thanks for posting the workshop Videos here.  I have been passionate about Indic Knowledge Traditions (IKT) since several decades. The readily available and much talked about Common Era IKS: (14-18-vidyāsthāna, śāstra categories, triskandhajyotiṣa, etc.) texts do not expound the natural (logical/scientific) growth and historical foundation of IKT that seamlessly integrates the external phenomenal and the internal mānasic worlds, although many CE texts, theories, schools, show a mix of the two; the intuitive and the deductive; the emotional and the intellectual. This is how, I got pulled towards the pre-rāśi; pre-vāra; pre-hora, pre-siddhānta period in search of the roots of IKT as an academic venture. Occasionally I have shared in Journal publications what I have found and understood. Currently, there is so much of glamourised narrative upswing,  about pre-modern civilizational history, Bharatiya Gyan (sic) Parampara, innovation-DNA, Vedic-science, Indian psychology, Governance, Jurisprudence etc through and by IKS as a new academic discipline in the university system. I am afraid this build-up may not stand the test of time if the more ancient knowledge base, even if it were to be difficult, is not studied and analytically stabilized. This is the motivation behind the IABCE workshop. IKS scholars and students, both traditional and modern, even if not interested in analysing Vedic astral observations, would benefit by listening to Prof. Pandurangi’s talk in the last video; Time stamp- 2:07:56-2:30:30.

Thanks

RNI

“…if the more ancient knowledge base, even if it were to be difficult, is not studied and analytically stabilized. This is the motivation behind the IABCE workshop.” (Emphasis added)

Thank you for detailing the motivation behind the workshop 🙏. All points noted and actually resonated, especially the points emphasised above.

I did listen to Prof. Pandurangi's views starting from ~2:09:25 in the last video (this link https://youtu.be/PCT5TH69QEI?list=PLnRbqoRbGaa0aeflLaYt0NssoKfMM8rW-&t=7765 would commence from exactly that moment)

🙏,

Megh
