Nicole Kidman has embraced the philosophy of a quirky Hindu faith which extols the power of a good hug. The Aussie Oscar winner was spotted at a recent gathering of Amma followers in Sydney. Devotees of Amma - real name Mata Amritanandamayi - believe hugs have healing qualities and help desperate people overcome illness and depression. Kidman reportedly showed up unannounced at Sydney's Subud Hall with a devotee of the sect - and stayed at the meeting with another 80 people for two hours. A bystander says, "She listened intently, smiled frequently and seemed very relaxed." Amma is believed to have hugged 30 million people since fronting the sect 30 years ago.
