would u question - why should only women be asked to have a mungalsutra? why not men? OR why join the two hands and not the two legs while praying? ....or simply why leave footware is to be left out while moving into a temple why not our clothes tooo.... When certain beliefs are followed by a major set of people lest try not to question that. if u have any radical thoughts better move out of it. Ayyappa is worshipped by men and those men live in extreme bachelor life in those days and there is a simple rule regarding women so be it.
