How did Sai Baba justify his requests for Dakshina by connecting the concepts of spiritual debt and past-life actions?

In Chapter 36, Sai Baba provides a multi-layered justification when questioned by Shama. He begins by establishing his own detachment from worldly wealth, then introduces the principle that "debt, enmity, and murder—these are not escaped by the doer even at the end of an eon." His requests for Dakshina were not for personal gain but were a mechanism for settling these inescapable debts. He illustrated this with the story of the man who had forgotten his vow to give his first salary of fifteen rupees to God. Baba's request for that specific amount was a targeted act to liberate the devotee from his vow. This demonstrates that Baba perceived and interacted with a reality where spiritual and karmic debts were tangible and needed to be settled for a devotee's ultimate welfare.
