Thank you arasi and amsharma , for the encouraging words.
But then what is the dharma of a singer? I mean, this feeling is so personal. You can never explain this to your listener. I know music can touch people at different levels. So, what is the first duty of the singer ....... Sing to the oneself or try to take listeners to your level. Sing only those songs which will give me immense pleasure (I really get high when I understand the song and sing) or sing those which the rasikas want?
I don't want to sound clichÃ©d - but should I not be true to myself and sing ?
Am I taking this discussion ..... some where else?
This is a hard question and you will probably find plenty of contradictory advice as on any substantial question in music performance.
It is (only) somewhat parallel to the question of whether you should shake your head or make other gestures when you sing. To some people this suggests total involvement, others think one should sit like a statue and let your music do all the gestures.
To make your question very stark, what is the difference between singing in a recording studio versus in front of a live audience. If there is no difference to you then you have nothing to think about -- that is your music and you are blessed. If you behave differently in front of a live audience then you are trying to communicate to your audience via channels other than your singing. Which is not a bad thing by itself but something to be aware of. Someone said to me a long time ago that a singer who does not cry himself but causes the audience to cry with the pathos in his music is better than the other way round. But this does not have to be either or, in my opinion. It is fundamental that you enjoy your singing, otherwise no one will enjoy it.
If you are overcome by the lyrical bhavam and the people who are listening to you are also overcome by the bhavam at the same time then you have hit the jackpot of music-making. So some risk of becoming overwhelmed yourself (to the point of disruption) may be quite worth taking.
