"It was a great gift the Maharishi gave us. For me it came at a time when we were looking for something to stabilise us towards the end of the crazy 1960s. I think it's a great thing." Sir Paul McCartney is grateful to MAHARISHI MAHESH YOGI for teaching him the benefits of meditation during a trip to India with his Beatles bandmates during their heyday. The legendary rocker will perform at director David Lynch's charity concert in New York on Saturday (04Apr09) to aid The David Lynch Foundation, which aims to promote meditation in schools.
