It took the Metropolitan Museum of Art nearly 50 years to wake up to Pablo Picasso. It didn't own one of his paintings until 1946 when Gertrude Stein bequeathed that indomitable quasi-Cubistic picture of herself - a portrait of the writer as a sumo Buddha - to the Met principally because she disliked the Museum of Modern Art.
Art is not necessary at all. All that is necessary to make this world a better place to live in is to love - to love as Christ loved as Buddha loved.
