Raga = Color, Hue, Beauty & Melody

Ragas, derived from Sanskrit word which mean act of coloring or dyeing (the mind and mood/emotions in this context) and therefore metaphorically means 'any feeling or passion especially love, affection, sympathy, desire, interest, motivation, joy, or delight.' 

Which is what one hears from the amazing Monterey Pop performance by Ravi Shankar, Alla Rakha  and Kamal Chakravarty at the top of their game almost 50 years ago. Take the time to listen to this masterpiece and be amazed at the modernity of music that started in India over 1100 years go. Astounding says it all.
