I believe that traveling offers the world’s largest classroom. Often, I travel to Toronto, Ontario (Canada) to visit friends. My visits have offered me the opportunity to meet many East Indians, experience their tasty cuisine, and learn a bit about the Sikh religion.
The turban (as most Americans refer to it) is called a dastaar. This headwear is an article of faith that represents self-respect, courage, spirituality, and covers their uncut hair.
Everyone that wears a turban is not someone that should be feared, and worse, treated with disrespect. I have found the humanity and humility of the Sikhs refreshing.
Keep traveling, keep exploring cultures different from those which you are comfortable. This can only make this world a better place.
