Hello, I would like to learn much more about the Khalsa initiation. I was wondering its religious significance in the tradition. Also, its relation with doctrines and history of the tradition, and how the Khalsa initiation ceremony is an expression of the tradition's beliefs. I researched into it and I know very little of its significance and how it relates. Also, if anyone knows any books or journals/ websites that goes in depth about the khalsa initiation ceremony, that would be great. Thank you!
