Re: Sindh Through Centuries!
I came to know that there were Sindhi Sikhs who also migrated to India. Read about murder of a Sikh near Ratan tala School (near Tibet Centre, Karachi) in Amar Jaleel’s autobiography (his childhood memories).

Nowadays, Udasipanth and the followers of Guru Gobind can be merged into one broader group of Nanakpanthis. The Nanakpanthi sect is a blend of the Sikh and Hindu religions. Almost all the Hindus of Sindh belong to the Nanakpanthi or Nanakshahi group. Although there are other sects too, namely Daryapanthis (followers of Darya Shah, aka Khwaja Khizar, Zinda pir Amarlal, Jhulelal and Uderolal as he is known by various names) and Nath Jogis (Shaivite renouncers).
