Some years ago, I read a book called Mere Christianity by C. S. Lewis. In it, he endeavored to answer the question, "After all the nonessentials are deleted, what must one believe to be a Christian"? Being a Christian, he was, of course, also trying to convince his readers to join his faith. We are not concerned with that, of course. All this controversy about Darshan Singh has gotten me asking myself this very basic question. If we strip all the nonessentials off, what must one believe and/or do to be a Sikh? I would start with accepting the ten Nanaks and their teachings and Shri Guru Granth Sahib Maharaj ji as our Eternal Guru. Even that leaves me asking questions. What does it mean to accept our ten human Gurus and now SGGS ji? At first I was going to add "living according to the Sikh Rehat Maryada," but that immediately falls short. There are other Rehat Maryadas, such as the Gurmat Rehat Maryada (Damdami Takhsal), and of course, all of these (I think) are open to revision. Certainly, I would like to see some changes to the SRM, which I use as my blueprint of the Sikh life. What can we all agree on (if anything) that a person must accept/do in order to have the right to call her/himself a Sikh? Can we please discuss this? What is "Mere Sikhi"? What is our faith/religion/way of life when stripped of everything that is not essential?
