Salatura

This suggests that Pāṇini lived in Śalātura, an ancient city in Gandhara, likely near modern-day Lahor, Pakistan,[4] a small town situated at the confluence of Indus and Kabul Rivers in the Swabi district of Khyber-Pakhtunkhwa, 20 miles northwest of the Attock Bridge.

[5] According to the CE 646 book Great Tang Records on the Western Regions (大唐西域記) of 7th-century Chinese scholar Xuanzang, there was a town called Suoluoduluo on the Indus where Pāṇini was born, and he composed the Qingming-lun (Sanskrit: Vyākaraṇa).

The arhat smiled pleasantly and in explanation said — You must have heard of the treatise on Etymology made by the rishi Panini and given by him to the world for its instruction.

He added that in his previous existence Panini had devoted all his energies to worldly learning but that from some good Karma he was now the teacher's son.

Panini describes in great detail the local accents used for the names of wells north and south of Vipasha (modern Beas) river.
