Dear Santhsh, we have to remember one thing that the Manu Smriti wrote in very many centuris before and accordingly the same had been, sometimes, manupulated or added. As on today who remembers here this Smriti and really it had gone to Vismriti. You say one thing who are here now as Shudras? The recent news says that now in Delhi there are so many brahmins doing cleaning jobs of toilets. (here you sense the thread weared persons as brahmins). At actual all jobs are sacred when we do it with devotion. All are working to earn their daily needs, and poojaris and the so called bhangees doing thing for livelyhood. What we left here otherwise we have some mercy to spare for others? Who is here for centuries? One after other our forefathers mingled with Panch Bhootas and accordingly we will too one day.
