Our golu is a thematic golu and the theme is Dhasavatharam. We could see Dhasavatharam at every home but this is not emphasized. This year we wanted to emphasize the importance of Vishnu Avatar and hence the theme is Dhasavatharam.
Also we have made a hand made life size or rather vishwaroopam idol of Mathsya Avataram. Perumal's head alone is procured and made out of wood and rest of the body is hand made with utensils at home.
We also narrate the story of Mathsyavatharam to people who visit us for golu with which we ensure they learn or hear a story of perumal which will add some value as well.
