Based on the source text, how did the combination of light, sound, and movement create a grand spectacle during the Chavadi procession?

The grandeur of the Chavadi procession was a multisensory experience created by the fusion of light, sound, and movement. Chapter 37 explains that light emanated from rows of lamps, torches held on all four sides, and fireworks like 'Nale' and 'Chandrajyoti'. The sound was a powerful force, with horns, trumpets, cymbals, mridangas, and drums creating a thunderous effect, layered with devotees' cries of victory and the continuous chanting of Sai's name. Constant movement added to the spectacle, with devotees dancing and jumping, the decorated horse Shyamakarna prancing, and chowrie-bearers fanning Baba. This dynamic combination of elements resulted in a procession described as both beautiful and incomparable.
