"The Brhatkathamanjari and the Kathasaritsagara I, 4, 20 relate the story of the origin of Panini's grammatical work. Panini, they say, superseded the Aindra grammar-Aindram tad asmadvyakaranam bhuvi-,pleased Siva and introduced navam vyakaranam. According to this tradition-jitah, panina sarve murkhibhuta vayam punah. Yuan Chwang indirectly corrects this later animadversion on Panini in Si-yu-ki I, pp. 115ft., nothing the testimony of his times more than a thousand years ago to the importance and popularity of the great Sabda-vidya of the immortal Salaturiya. In any case, for the last two thousand years, Sanskrit grammar as the key to Sanskrit language and literature means practically Panini as supplemented by Katyayana and Patanjali. Generations of students in India and abroad including Asia, Europe and America, have found the Astadhyayi to be the most accurate and scientifically described account of the Sanskrit language.
Within recent centuries, however, a change has come over its study in India. While in Europe, Goldstucker, Liebich, Kielhern and Skold have maintained and continued the Panini-parampara, in India, specially in the North, Bhattoji's Siddhantakaumudi has replaced the Astadhyayi." (jacket)
