A monotheistic faith preaching the principles of equality and service to others, Sikhism is fairly young. But in today&rsquos tumultuous times of human conflict and warfare, the philosophies of universalism, public service and the ideology of one god&mdashwhich are central to this religion&mdashseem a little too relevant. As per the Sikh faith, prayers can be offered anywhere, but gurudwaras were particularly built for congregational worship.
