I had not visited this blog spot for  over three years and somehow I thought I should visit it and update it. I found one draft contribution which I corrected and posted today. 
Having published something after a gap I thought let me place my random thoughts here and perhaps start publishing regularly in this Bharathanatyam  Knowledge section regularly
In the interim I did get a chance to visit a  number of dancae programs both offline and online  and I am much impressed with the grand revival of the art among the youth today which is more than refreshing. The Generation X has taken to art in a big way. I find today far more number of  artists today than any of the decades that I saw. And when it comes to Dance and Music there is an amazing variety of dancers of all age groups and nationalities which is overwhelming. The fusion era also seem to be over with the newer  disciples showing a propensity to  learn and practice Pure  Dance forms rather than  mix and match  without any  grammer or structure. 
Part of the reaons for this, the passing of the previous generation of Dance Gurus who were  not open to suggestion or cricism of their way of practicing the ancient art form. Now the  kids with  exposure to a vast variety of performers thanks to the Net platforms   they are questioning the Gurus of the purity of the art which is a good thing
Also I find younger Gurus are also ready to  work  with the youth to  teach and also to learn which is also a good thing.   The stranglehold of the Sabhas have also ended  except for a fancy few. 
Going forward the Dance studios that are being founded everywhere should focus on collaborative research and experimentation.  Already the young artistes and their parents are demanding the learning does not stop at  three or four stages of the Margam which comprises of Seven stages or learning. The seven styles of Bharatnatyam are Pushpanjali, Alarippu, Jatiswaram, Shabdam, Varnam, Padam and Tillana. The students would also have to learn 
Tatta Adavu: Teaches the Bharatanatyam style of leg tapping
Kutta: The toes stamp the ground while the heel is raised
Tadita: The heel holds the ground while the forefoot stamps it
Mardita: The sole rubs the ground
Sakhalita: The foot slips on the ground
Jaati Adavu: A pattern denoted by a set of syllables, such as Tishra, Chatushra, Khanda, Mishra, and Sankeerna, Beside these,  , Natta Adavu, Tatti Meeti adavu, Tirumanam Adavu, Murka Adavu, Jati Adavu and Kuditametta Adavu need to be learnt. 

    The dancers also have to learn the nuances of bringing forth the 9 emotions  or Navarasams, namely  love (shringaara), laughter (haasya), kind-heartedness or compassion (karuna), anger (roudra), courage (veera), fear (bhayaanaka), disgust (bheebhatsya), wonder or surprise (adbhutha) and peace or tranquility (shaantha). All the 51 mudras have to be learnt flawlessly
We can certainly look forward to a Golden Era of  traditional Dance forms going forward.
