Pilgrimage to Sufi saints' shrines is, temporally, a search for union with God. The ritual of visiting any place of significance is called ziyarat; the most common example is a visit to Prophet Muhammad's Masjid Nabawi and grave in Medina. The Chishti order was the first of the four main Sufi orders (Chishti, Qadiriyya, Suhrawardiyya and Naqshbandi). It derives its name from Chisht (pronounce: Chesht, hence Cheshti). Chisht is a small town near Herat in Afghanistan.
