The source material mentions three types of humans: gods, demons, and the greedy. How are these defined, and what specific instruction from the syllable 'Da' applies to each?

Chapter 14 explains that these three types are different kinds of humans based on their nature. The 'gods' are defined as humans endowed with noble qualities and self-control; their instruction from 'Da' was 'Danta,' meaning to be self-controlled. The 'demons' are described as humans who are violent, wicked, and cruel; their instruction was 'Daya,' meaning to be merciful. Finally, there are humans who are gripped by difficult greed; their instruction was 'Dana,' meaning to give charity. Baba uses this framework to guide devotees, with Sai Nath specifically helping the greed-oriented person.
