David Lynch, who directed “Eraserhead” and “Blue Velvet” and created the cult TV hit “Twin Peaks,” has taken on a new role, that of meditation advocate.  Turns out, David Lynch discovered Transcendental Meditation back in 1973, and he credits his practice with keeping him both grounded, and open to the creative gifts of the Universe.  In 2005, Mr. Lynch started the David Lynch Foundation, which finances TM scholarships for students in middle and high schools to study meditation.  Since that time he’s been lecturing on college campuses to spread the word.  And now he has a new book: “Catching the Big Fish: Meditation, Consciousness, and Creativity.” It’s a kind of autobiography, filled with stories of both his career and his experiences with meditation.  David Lynch is certainly passionate about filmmaking, and he’s passionate about meditation, too.  Here’s one of the lines from the book: “If there were ten thousand new meditating students, it would affect this country.  It would be like a wave of peace.  It’s harmony, coherence, real peace.  In the individual, that light of consciousness drives negativity further and further away.  In the world, it can do the same thing.
