I've learned quite a bit about Sikhs and Sikhism as part of my job hosting the tv show 3D Dialogue. Their committment to freedom, equality, and liberation is incredible, and still to this day they've kept their culture alive and vibrant, while still relevant to the modern world. These two segments are an interview with Jaswinder Singh about the Nihang Sikhs and the martial-art Gatka, which they practice.
