Sow.Sri.Renuka,
Somehow I have a feeling that you may not know the 'ritual' about 'oil bath'. Assuming that you may not know (I know, dangerous), let me explain the ritual.
It takes about 350 to 400 mls of oil for my frame (long hair, பனை மரத்தில் பாதி உயரம்- means tall). Firstly, the oil (usually sesame seed oil) has to be warmed up. Usually the most innocent in the family would end up doing the task of applying oil. Before starting to apply the oil, nalangu would take place. Most of the oil would be in the hair dripping down the face with impurities. I have to soak the oil in. Then, using 'sikaikai powder, soap, shampoo, hard labour, warm water and a lot of swearing, I would get rid of the oil grime from the hair and the body. (this is where the glamour comes in. lucky boys get their would-be, girl friend, girl in love..may have her to rub the back. In my case, I had the servant to do it. His usual comment would be 'எருமையை தேச்சு உடற மாதிரியே இருக்கு'.
I will be very hungry by now. Big lunch would be followed. Then a nap in the afternoon. nap after oil-bath is bad. So I would complain how bad I feel after the nap, I would choose to eat a 'light meal' for dinner comprised of yummy பலகாரம்ஸ். This is the ritual of oil - bath.
Cheers!
