The following are my questions on this topic.
What are the Navabhashanas in the Palani Murugan Idol consecrated by Siddhar Bogar?
Where are the ingredients of Navabhashana sourced from and what is their physical and metaphysical significance?
What is the best available Scientific understanding of process of solidifying the Navabhashanas?
Also, Is there any original(or earliest) photos of the Palani Idol available before it was ravaged with scratches and etchings by devotees and alternative medicine seekers?
