Waiting to read the "Sol valar kadu"! Your outline of what you plan to write suggests that this will be one of the best philosophical treatise - an extension to the "6 Dharsana",
The mysterious, yet embracing, standing still yet full of life, the Aranyam is the right analogy to explain the "sol" in conjunction to Veda. How Pandavas shape up during their stay in the Vanavasam and how they understand and develop thru "sol" kindles more interest. Also looking forward to read your interpretation of the Yaksha Prasna .
Warm Regards,Sobana Iyengar
