In page 67 of the book "The Doomsday Conspiracy", Sidney Sheldon says
"Yes, They did an experiment at Temple Buell College in Denver where healthy flowers were put in three separate glass cases. Acid Rock music was piped into one case, soft East Indian Sitar music was piped into the second case, and the third has no music. A CBS camera crew recorded the experiment, using time-lapse photography. At the end of two weeks, the flowers exposed to the rock music were dead, the group with no music was growing normally, and the ones that heard the Sitar music had turned into beautiful blooms, with stems & flowers reaching toward the source of the music. Walter Cronkie ran the film on his news show. If you wish to check it, it was on October 26, 1970"
But why did he mention as East India rather just India. Probably if he had mentioned as 'Indian Sitar' music, the western world would think it is a music of american Red Indians. They even don’t know the name Red Indians was derived because of us. I think, the day Columbus landed in the west was the Doomsday where we not only lost our richness but also the richness of the word 'India'.
Anyway, experiment proves that our Sitar music is simply the best music even nature likes :)
