I am 78 years old
This has been tradition in our house for 90 plus years from my mother in law's times
There is no specific theme other than the fact that most idols are been our family heirlooms , some more than 80 years old
The three seperate sections, with similar themed idols together,like andal story, dasavataram, great gurus, village, shivas wedding etc
It's not a fancy golu, just a simple one and like Chennai, it's a tradition, simple elegant and unchanged culture over time!
