the majestic golden temple, the sikh equivalent of the vatican. sikhs are fundamentally against any caste system, believers in religious tolerance, but they are just as fundamentally war-like when it comes to defending their principles and what they see as their territory. >> welcome to golden temple. >> thank you. >> today is gurpurb one of the most auspicious days of the sikh calendar. pilgrims from all over the world come to worship, walk the perimeter and bathe in the holy pool. all are welcome of any faith or caste to remove their shoes, wash their feet, cover their heads and take part in a simple meal. ♪
