"The opening and ending image of the book, is used to symbolize Punjab, namely Sikhs driving trucks. It also symbolizes someone who is to travel. In this context, it's me 17 years old, and the load carried is my identity being fueled. The truck is very typical of Punjab, and most drivers are Sikhs. So they set a very clear mark on the appearance of the vehicle. I chose to use just that to make the book into a unit. It symbolizes a start and an end. It makes sure you get a red line through the book, and the symbolism: Everything I experienced is inside the truck, and the truck was always on move."
