At the end of the cosmic dance Lord Shiva the Lord of dance, sounded his damaru fourteen times.

For the sake of the upliftment of sages like sanaka. 

According to legend, these sutras were written by Panini upon mystically hearing the beats of Siva-Nataraja’s damaru (hourglass-shaped drum).  It has been said that the mantra is God in the form of sound.  Therefore, words are an extension of that power. The tantra stresses the importance of sound as a divine substance and vehicle for salvation.  And hence, entire cosmos is in the form of
 these sutras.The 14 sutras are (in ITRANS format):
