Very mature of you Anil. I really appreciate your analysis. I would like to sincerely clarify that there is absolutely no conscious effort to be self-righteous in my approach. Well it was just my understanding which may not be correct and should be subjected to critical analysis. Floor is all yours to offer your critical comments. Both of your posts are very valuable and thoughtful and I really admire your analytical strength and intellect. Please keep sending your views. Thanks. However, I owe an explanation to you on certain points of divergence with you and it will be forthcoming in due course.
