We are talking about a subject no one knows,What is menses?.It's a natural process by which the nature tells a women that you are qualified to be a mother.In Kerala people use to celebrate "THEENDARI".Let me ask you if your mother did't have menses you won't be here to protect "SABARI MALA".We all are here because our mothers had "ARRTHAVAM".So if you say "ARRTHVAM"is un clean that means you yourselves are UNCLEAN&ROTTEN.
