My mom always scolds me whenever I comb my hairs after sunset. The reason that she would say is “Lakshmi (God) will not come home if you comb after sunset”. Traditionally, we lit the lamp in pooja room and keep the main door open so that Lakshmi (God) would come to our home and bless with health & wealth.
But today, nobody would keep the doors open in evening. It’s not becoz they don’t want Lakshmi to come home.. but becoz of the mosquitoes. We shut all windows and doors once sun sets.
Ok. now what could be the technical reason behind my mom’s scoldings. My theory is below
In olden days, we did not have electricity. The oil lamps could not make the entire home bright. We couldn’t use many oil lamps too. There would be max 1 per room or 1 per house used (depending upon their economic situation). Therefore, if you would comb your hairs in evening, you cannot collect all the fallen hairs from ground and they can fly and also get into the food we eat (Remember we sit & eat on the floor those days and not in dining table).
I also say my theory to my mom whenever she scolds me. But she would just say that I am talking like my dad.
