What is the symbolic meaning of Baba extinguishing the fire before the Chavadi procession? Does it relate to calming worldly desires?

While the source material describes Baba's actions with the fire, it does not explain any symbolic meaning, such as calming worldly desires. According to Chapter 37, before setting out for the Chavadi, Baba would go to a wall where firewood was kept. He would move His right big toe at that spot for a moment and then, after personally waving His right hand over the burning flame, He would first extinguish it and then set out. The text focuses on the physical actions Baba took as part of the ceremony, rather than providing metaphysical interpretations. The procession would then commence with music, fireworks, and great fanfare.
