Dear Learned,
I had similar question but I think I could deduce answer to my question from the post. Thanks to you all. Though I had guru upadesam and attended couple of classes, I'm currently not reciting rudram. Unfortunately, I had to move to a different city and I asked my guru if I could recite it on my own. I did not get any response, so comprehended as I can't. However, my guru does mentor interested students (absolutely free though) on phone or skype every weekend. Its just due conflict of time zones I'm unable to benefit. I for one, do not want to experiment as I fear of swara dhosham.
regards,
Kumar
