Last year, Kalakshetra  had organized a five day workshop, where the scholar Bharat Gupt  discussed about and on Natyashastra. The entire lecture duration was for 25 hours! For those who don’t know him, he retired as the Associate professor from University of Delhi. He is described as Indian classicist, theatre theorist, sitar and surbahar player, musicologist, cultural analyst, and newspaper columnist .
In his own words 
The lectures-interactions provided a detailed exposition of all the principles of performance in each of the 36 chapters of the NS and related them to the present genres of performance such as plays, cinema and sculpture. The text and the ensuing discussion on it is made a spring board to analyse and contrast many classical ideas with Indian modernity not only in the area of performing arts but in the approach to life as a whole.
Related paradigms of Hindu performance such as leelaa, avataara, charitra of gods as human, concepts of saguna and nirguna worship were closely related to the ethos of NS performace. Limitations of religious cultures that do not allow mimesis of incarnation or depiction of holy lives were also discussed. Puritanic, secular or propagandist approaches to art, and drama in particular, were contrasted with the Vaishnava ethos that allows full scope of depiction of the divine as human and the human as divine.
After the workshop he had reported that 
[He] spent some ‘glorious days’ there. Thrilled with the entire ambience of the campus and the way activities were being conducted amidst the throb of a ‘happening’ place, he was delighted with his interactions with the informed and very eager students asking him intelligent questions.
