The soles of the feet are considered one of the Upāngas, or minor limbs.
The movements are used not only for the precise control in the execution of Nritta but also to communicate meaning in the context of gesture.
Please refer to the Shloka below for pronunciation. Please note that the separate movements of the head when put together in a Shloka form 'Sandhis', or compound words in the Sanskrit language. Words like 'ca', 'thatha', mean "and", "also". The separate words for each movement are also given below the shloka.
