Can you explain the story about Prajapati and the syllable 'Da' and how it connects to Sai Baba's teachings?

Chapter 14 recounts a story where Prajapati gave a one-syllable instruction, 'Da,' to his three children: the gods, the demons, and the humans. Each group interpreted it differently based on their nature. The gods understood it as 'Danta' (be self-controlled), the demons understood it as 'Daya' (be merciful), and the humans understood it as 'Dana' (give charity). Sai Baba applied this ancient wisdom to his own devotees. The text explains that Baba, through this letter 'Da,' was asking his followers to be merciful, give charity, and be self-controlled to attain extreme happiness. This was considered a simple remedy planned by the Guru to help the disciple overcome the difficult-to-conquer faults of lust, anger, and greed.
