Based on the text, what were the specific sights and sounds that made the Chavadi procession such a vibrant sensory experience?

The Chavadi procession was a feast for the senses, filled with spectacular sights and sounds. Chapter 37 describes the auditory landscape as being rich with the resonance of mridanga and veena, the clash of cymbals, 'Tas', and 'Jhanj', and the blowing of horns and trumpets. This was accompanied by the constant chanting of Sai's name and cries of victory. Visually, the scene was illuminated by torches on all sides and brilliant fireworks like 'Nale' and 'Chandrajyoti'. Devotees carried colorful banners and flags, some displaying the 'Garuda-tak'. The fully adorned horse, Shyamakarna, with jingling bells, and the golden-bordered shawl on Baba added to the magnificent spectacle.
