What significance does the repetition of the world of raga have in this excerpt from "unanimity has been achieved, not a dot less for its accidentalness" by bob kaufman?

Raga is a piece of Indian music that is rhythmic and used spontaneously.

The use of repetition in the line "I sing a mad raga/I sing a mad raga/a glad raga...is being used as a sort of call to arms, a mantra, a chant for equality in our society. It is something that people could copy and easily remember. 

The use of reception of the word is also a form of anaphora. Used before each new idea, it makes the idea itself stand out. raga of yellow/raga of mellow/raga of new/raga of old/raga of blue/raga of gold.

The details about the statues, i believe, are that they're carved from blocks of igneous stone, many of them are partially buried under the ground which to preserve and protect them from the harsh environment on easter island, and many of the facial features have washed away. also, the most well-preserved one is at the british museum in london.these are just guesses from what i can see and what i think i read correctly. i'm sorry i couldn't be more .
