"I got that idea from being in India. I always like the chanting"

Ray Davies' quote is likely referring to his experience in India, where he was exposed to the chanting of Hindu mantras and prayers. This experience likely had a profound effect on him, as he was inspired to include the shouting into his own music. He likely discovered the shouting to be soothing and serene, and wanted to bring that exact same feeling to his own music. He might have also been motivated by the spiritual element of the chanting, and wanted to bring that exact same sense of spirituality to his own music. By including the chanting into his own music, he had the ability to create a special sound that was both soothing and spiritual. Ray Davies' experience in India likely had a lasting impact on his music, and his quote is a testimony to that.
