David Lynch’s movies may be edgy, but he has reason to be mellow behind the scenes. The “Twin Peaks” mastermind hasn’t missed a day of meditation in 40 years. Lynch, 67, said at a recent gala for his foundation at the Conrad Hotel that he began Transcendental Meditation in ’73 and hasn’t stopped. “Twice a day, every day.” The benefit honored Hugh Jackman, his wife Deborra-Lee Furness and FDNY Commissioner Salvatore Cassano. Jerry Seinfeld, who’s practiced TM for 41 years, entertained the crowd.
