Why did Sai Baba ask for Dakshina and then use it for charitable deeds and buying firewood for the Dhuni?

The source material from Chapter 33 of the Shri Sai Satcharita outlines a specific cycle in Baba's routine. It mentions that he was "again and again asking for Dakshina" and also "performing charitable deeds for the poor and destitute." In the same breath, it describes him "buying firewood bundles from those who had surplus" and offering these logs into the sacred Dhuni. The resulting ash, or Udi, was then distributed. The text links the giving of Dakshina to cultivating renunciation in the devotee, which is the first step. The Udi, which is the end product of the firewood bought, symbolizes discrimination. This suggests Baba's actions were a living lesson, guiding devotees from the initial act of giving towards the higher spiritual states of renunciation and discrimination.
