Panini

Son of Pani. A palm reader prophesied to Pani that his son would remain stupid as his palm lines showed no signs of intelligence. Pani tried hard to teach his son, but the palm of the hand’s testimony turned out to be true.

Panini went into meditation on Shiva and Shiva appeared to him, beating his drum fourteen times. The vibration of the sound went deep into Panini, for him it was the revelation of the sound of Sanskrit. The fourteen strokes are known as Maheshvara Sutrani and became the basis of his work Ashtadhyayi.
