An important Buddhist shrine helped to make the city a centre of pilgrimage until the 7th century.Pushkalavati, in the Peshawar Valley, is situated at the confluence of the Swat and Kabul rivers, where three different branches of the River Kabul meet.
There are some legends in which the two rivers are said to be joined here by the underground Sarasvati River, forming a triveṇī, a confluence of three rivers.
However, Rigvedic texts, and modern research, suggest that the path of the Sarasvati River was very different.
Gandhāra was an ancient Indo-Aryan mahajanapada ("great realm") situated in modern day northern Pakistan, in the Peshawar valley and Potohar plateau, and extending to Jalalabad district of modern-day Afghanistan.
During the Achaemenid period and Hellenistic period, its capital city was Charsadda, as well as the Zoroastrian Avesta, which mentions it as Vaēkərəta, the sixth most beautiful place on earth, created by Ahura Mazda.
That specific place is still called Prang (from Prayāga) and considered sacred; local people still bring their dead there for burial.
