Kerala- place where officials founded lots of treasure is under travencore royal family till 1947. In that time itself it was very active in business which is used to do 100 crores of business. It had active business relationships with Netherlands and also with England. ( especially in dealings of 'Thorium' - metal used in Nuclear weapons ). All the trading was done by Travencore kings especailly Raja Marthanda varma, strategically executed by dewan ( Minister ) C.P. RAMASWAMY AYYAR who was a lawyer. He was well known as guradian of national treasure with his strategies.
In 1947 when nation got the freedom, there was 565 royal families existed, among them 6 families are not agreed to merge with India. Travencore stood first among them. C.P.RAMASWAMY AYYAR wanted to make travencore as an independent nation but he couldn't do so.
Once Raja Marthanda Varma left his positon as king and named himself as Padmanabha Dasa ( slave of Lord padmanabha ) his family also followed him and till how they add Padmanabha Dasa before their name, in case of females in the family know as 'Padmanabha sevaki'.
Interestingly he announced that all the wealth of Travencore belongs to Anantha Padmanabha Swamy temple, not even single penny belongs to royal family. From then his family took responsibility of securing wealth.
NOW, the Government ordered to count the wealth of temples and Kerala's Lord Padmanabha Swamy temple shook the records with one lakh crores from 5 underground treasure room and one not yet opened as it completley built by iron walls and doors.
So, no one don't know what exactly exists inside the door?, it is a million dollars question...
