The youngest of the world's seven largest religions is Sikhism, founded in Punjab in the 16th century. Nanak, a guru, or teacher, from outside Lahore, spent three days lost along a river and returned with an undestanding of one God: the Ultimate Reality. Nanak created a religion founded on equality, service, and openness, yet his successors would soon find themselves under attack from vested interests, particularly the Mughal Empire.

In this episide, we visit the Golden Temple, or Harmandir Sahib, their holiest shrine. It is a brilliantly gorgeous golden temple surrounded by a tranquil pool, visited by a steady stream of devoted Sikhs. We'll recount some of the challenges the Sikhs have faced, challenges which have made them fiercely willing to defend their people and their faith.

And of course, we'll include that most famous Punjabi dish: tandoori chicken, or at least as close as we can come without an actual tandoor!
