Yes, indeed. Thanks cool! There is a lof there to think about. I think I know why Cool created that analogy though I do not know much about the intricacies of HM. Cool is uniquely
qualified to come up with such superb and appropriate metaphors.
Now how do I fit in my RTP thought experiment to figure out how far the two systems are fundamentally. Cool's analogy seems to
address the performance and development aspects of a HM concert vs a CM concert which fits in nicely with my RTP thinking since the two systems converge to
some extent on those two aspects at the RTP. ( railway traffic point

One obvious implication is that it should be a piece of cake for a HM musician to learn to sing an RTP in CM Bhairavi. But I am still curious if the gamakas and laya may be the high learning
curve. Not that I know they are but if they are, that will tell us about the accumulated evolutionary differences between the two. ( The reverse has to be analyzed too )
