On December 8, 2003 The Arizona Republic reported that a new gurdwara in Phoenix will be the focal point for the Valley's Sikh community, which has grown steadily in this neighborhood for the past 30 years. The Valley is home to more than 1,000 Sikh families from Glendale to north Scottsdale to Mesa, many of whom recently emigrated from India in the late 1980s and 1990s for jobs in the high-tech industry. The community also includes American-born Sikhs who were first introduced to their form of spirituality in 1969 when Yogi Bhajan came from India to teach yoga to hippies. The "village concept" centering life around the gurdwara is traditional and exists in Sikh communities all over the world. Sikhs trace the model to the community of their founder Guru Nanak. American-born Sikhs like Khalsa were first introduced to their form of spirituality in 1969, the year of Woodstock, when a man named Yogi Bhajan came from India to teach yoga to hippies.
