The sangh was the organised pilgrim party: a group from a village or a set of villages walking together to a distant shrine, with a leader, a standard, provisions and a fixed route and season.
The Sakhi Sarwar sanghs walked from the central districts to Nigaha in Dera Ghazi Khan, five hundred kilometres and more, and back. Others went to Multan, to Pakpattan, to Hardwar and to the Devi shrines in the hills.
The journey was the point as much as the destination. A sangh took weeks, camped, sang on the road, and returned with a standing in the village that lasted.
The Devi pilgrimages to Jwalamukhi, Chintpurni and Naina Devi are the surviving form on the Indian side, still walked in jathas with a red cloth.
The long-distance sanghs west ended with the border.
The roads that carried them are the same roads that carried the armies, the traders and the refugees, and nobody has traced any of them.
A sangh is a party travelling together to a shrine, organised in a village, on foot or now by bus, with its own arrangements for food and shelter on the road.
The walking parties to the hill shrines, and to Pakpattan before 1947, were the ordinary form of long distance travel for most people, and they ran on established routes with known halts.
The routes west stopped in 1947. What was a walk of a few days from central Punjab to Pakpattan is now a visa application that is usually refused.
