pandit ravi shankar

today our digital communication professor told us about pandit jii's concept of tuning his audience before his show. pandit had come two hours before the show's start but then he went into meditating and then went 15 minutes late. when asked why his reply was,"they were not tuned to listen to my ragas thats why i took time and tuned them". i don't know if all this tuning and all is a valid concept but if the story is true then there must be something true about it.
