George Harrison's discovery of the sitar and Indian music was apparently accidental. He saw a sitar lying around in the studio when they were recording Norwegian Wood for the album Rubber Soul. In search of an exotic sound, he picked of the sitar, fiddled around with it and then delivered the now well known sound for the song. And created a new musical genre - raga rock!
We who have learned better would know that there are no accidents. There is a pervasive intelligence guiding everything that happens. Harrison was a seeker. He was guided to his answers through a cheap prop sitar lying around in his recording studio.
Determined to learn the instrument properly, he managed to get an audience with the maestro Ravi Shankar, who agreed to teach him. So off he went to Bombay (now Mumbai) where he spent 6 weeks under Ravi's tutelage. This was even before the Beatles had met Maharishi Mahesh Yogi, a meeting which brought all of them to Rishikesh one year later.
