Can you explain the teaching of Prajapati and the single syllable 'Da'?

The story of Prajapati, as recounted in Chapter 14, is a profound teaching on tailored spiritual instruction. When his three children—the gods, the demons, and the humans—asked for guidance, he gave them all the single syllable, 'Da.' The gods understood it as 'Danta' (be self-controlled), the demons understood it as 'Daya' (be merciful), and the humans, who are gripped by greed, understood it as 'Dana' (give charity). Prajapati affirmed that each had understood correctly, illustrating that the path to betterment is unique to the vice one must overcome.
