Ashtadhyayi has an important place in all the books of grammar. There are eight chapters in this Ashtadhyayi and each chapter has four padas. Altogether there are thirty-two padas. There are about 3993 sutras in the Ashtadhyayi. It is a supernatural miracle of Panini and his genius to fill a lot of meaning in very small sutras.
This small formula, leaving the small form, later assumes such a vast form that the entire Sanskrit literature, appears to be imbued with it. Panini's profound talent is echoing in each Sutra and teaches readers to memorize texts like Ashtadhyay.
