Everything changes with time. I don't know what you define as the Guru Shishya parampara. They are my extended family. If you mean they are not staying with the guru and embibing the art form I think that is not possible today. Formal education has become part and parcel of everybody's life.
Tradition is something which always evolves and changes.
Today you see a changed form of the same parampara. Because in the begining of the last century when the classical dance forms underwent a rennaisance these govt outfits came into being but with changing times the dancers have increased in number and the competition is between styles and within styles is stiff. I don't think the Govt bodies have been able to adapt to these changes and I think the main problem lies in the lack of transpirancy in the way they operate and function. Hence, many youngsters are deffident about taking classical music or dance as a full time career. Be it music, dance, theatre etc especially for Bharatanatyam.
