Can you explain the story about the syllable 'Da' and what it has to do with different types of people?

Chapter 14 recounts an instructive story about Prajapati, who gave a single-syllable instruction, 'Da,' to his three children: the gods, the demons, and the humans. Each group interpreted it according to their inherent nature. The gods, who were self-controlled, understood it as 'Danta' (be self-controlled). The demons, who were cruel, understood it as 'Daya' (be merciful). The humans, gripped by greed, understood it as 'Dana' (give charity). The text clarifies that these are not different species but three types of human temperaments. Sai Baba used this same principle, teaching his devotees through the letter 'Da' to be merciful, give charity, and be self-controlled to find ultimate happiness.
