Superb, Enlightening Articles -As ALWAYS!
I have Ketu in the 8th house, with Meena Rashi 8th Lord Guru in the 4th. A student of Jyotisham the 'ulta' way, I learned chart-analysis from the web and other sources. Though a 'madrasi', only prefer DIAMOND charts! A Lord Shiva-bhakth and a proponent of Veda mantraas, cannot stand non-professionals reciting Veda mantraas [Shani in the 5th house].
My Vimsamsa chart has stunning placements -Dhanu LL Guru in the 5th, 9th Lord Sun in the 9th, 2L Sat with EXALTED Mars, 6th and 7th Lords Venus and Mercury having exchanged places. Experienced coloured Vibhoothi many times in my small temple, especially when concentrating on beeja mantras, Nakshatra Sukthas and Rudra Mantram. Have a photograph of an OM sign on Sai Baba's photograph, including the forms of Lord Ganesha. My shastaang Namaskaar at Shri Rao's feet. Om Namah Shivaaya! Om Namo Narayanaaya!!!
