Sheryl Crow checked into an ashram and took a vow a silence in an effort to return to a positive mental attitude after her breast cancer scare and becoming single. The rocker was at her lowest earlier this year (06) when she was diagnosed with breast cancer just weeks after ending her engagement to cyclist Lance Armstrong. And as she was recovering Crow opted to seek spiritual help in a religious retreat. She says, "I've always been on a spiritual quest - I meditate, I went away to an ashram and took a vow of silence for six days and that was really one of those refining moments... It definitely helped me through this process."
