First, Thyagaraja is a great composer, perhaps even the greatest Carnatic music composer. What I am going to say is about us, not about Thyagaraja. So, I request dear members not to think of this as casting aspersions upon the great composer and feel hurt.
Is it possible to enjoy, respect, and even adore the genius of our ancestors without deifying them, elevating them to the stratosphere and forbidding honest assessment of his/her life? We find equal geniuses in the west, like Mozart and Beethoven, their music is no less adored, but they are not worshipped. Their life stories are not beautified.
Newton is arguably the greatest scientist the world has seen yet, but his dalliances with alchemy is not swept under the rug. They even celebrate the greatest blunders of the greatest scientists, e.g. "
Brilliant Blunders: From Darwin to Einstein - Colossal Mistakes by Great Scientists That Changed Our Understanding of Life and the Universe".
Why do we feel the urge to have only hagiographies and feel hurt with biographies? Gandhi's life comes to mind -- mention Mahatma's ugly side and the hammer of great soul will come down upon you before you have time to blink -- we saw that sometime back in this very forum.
This is not about Thyagaraja at all, it is about us, why must we be afraid to take a critical look at the life stories of our heros? What we find may not be picture perfect, but a nuanced understanding of their biographies can only benefit us by reminding us that our own shortcomings need not be an obstacle to do our best to excel.
Deifying them will take them away from us into the stratosphere. I feel by deifying Thyagaraja we lessen his genius -- i.e. his genius is not his but divine. Deifying him makes him a little less of a role model for the next Thyagaraja in the wings -- i.e. he is god and who am I to dream I can be like him.
Thyagaraja's personal failings, if there were any, only make him more endearing, more human, more like us than gods. There is nothing to feel hurt about that, I think.
