I am against it.
I don't see the need to change the existing rules.
Ayappa swamy oru bachelor Anu, adu Karnam purushanmaaru avide pookunnu. Pandu ee temple-inde chuttum, koddum kaad/thick forest aayirinnu. Avide sthreekal pokunnadu dangerous aayirinnu- iddum aavvaam avide sthreekalkku praveshnam nishedikuvaan ulla kaarnam.
I guess in my family(maternal and paternal) not many support such changes.
I still wear settu-mundu when I visit guruvayoor temple, ladies in my family are very particular about not wearing colourful sarees or the chudidar suits to guruvayoor. And the same rule applies to our Tharvadu temple too.
As a child/teenager I used to wear the typical kerala
pavadas to this temple.
Suddenly I feel so nostalgic. Hehe
