LONDON: Rock star Sheryl Crow moved into an ashram and vowed to remain silent for six days to return to a positive mental attitude after her breast cancer scare and break up with cyclist Lance Armstrong. The rocker was going through one of the worst phases of her life when she was diagnosed with breast cancer just weeks after ending her engagement to Armstrong. To get out of this dilemma, she opted to seek spiritual help in a religious retreat, reports contactmusic.com. 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.”
