Ashtamangala Deva Prasna
This is a popular article and has been published several times. It first appeared in an anthology of Astrology called Lessons in Hindu Astrology (1997). It then appeared in Diamond Fire Journal (1997) and again appeared in the Indian Vedic Astrology monthly magazine Express Star Teller (May 1999). This is what one reader from Belgium had to say in relation to this article:
Dear Shyamasundara,
Namaste. I have picked up your name from Lessons in Hindu Astrology, as the only one that looks to me as belonging to a person clearly possessing that serious, spiritual frame of mind, which I think to be essential for a practice like that of Jyotish.
I have been dealing with Jyotish for a long time now, but only as a private kind of interest. I have always kept apart from common astrologers, since I find many of them lacking any truly spiritual background. This is why I am addressing to you, although you live so far away from Europe. Do you happen to know of any serious Jyotish student in Belgium? If you do, will you give me his address, telephone, e-mail?
For the time being I stop here, with many thanks for any help you can give me.
Roberto.
The Fallacy of the trans-Saturnian Planets
This article appeared in January, 1998 edition of The Astrological Magazine, Bangalore, India. It is aimed at the more advanced student and discusses some of the foundational topics of Vedic Astrology. After receiving this article Gayatri Devi, the daughter of Dr. B.V. Raman and present editor of the Astrological Magazine, wrote me and commented:
"Father [B.V. Raman] liked this article very much, it is exactly in keeping with his own opinions."

Varaha Mihira
I recently read a very mangled version of how Varaha Mihira got his title "Varaha" or hog/boar so I thought I would post an official version.
