Amar Das is the Guru who turned a following into an organisation. He was seventy-three when he took the seat and ruled for twenty-two years, in which he set up the twenty-two manjis — preaching districts — and appointed women to head some of them, established Goindval with its stepped well as the first Sikh pilgrimage site, fixed Vaisakhi and Maghi as gathering days, and made eating in the langar a precondition of an audience with him. His social rulings were explicit: no sati, no purdah, widows may remarry, and Sikhs should not intermarry on the basis of caste. He also composed Anand Sahib, which is why the Sikh wedding is called Anand Karaj. Sikh historians note the obvious tension — the man who abolished caste rank in the langar also passed the Guruship to his son-in-law, and it stayed in one family for the next two centuries.
