How did Baba's teachings, particularly the 'Da' principle, help people overcome personal faults?

Chapter 14 explains that Sai Baba employed the principle of 'Da' as a simple yet profound remedy for a disciple's spiritual progress. The three interpretations—Danta (self-control), Daya (mercy), and Dana (charity)—were specifically targeted to destroy the three major faults that hinder self-progress: lust, anger, and greed. The text acknowledges that achieving victory over these negative traits is extremely difficult. Therefore, the Guru planned this 'one-syllable simple remedy' to help his followers. By encouraging his devotees to practice self-control, mercy, and charity, Baba provided a direct path to conquer these inauspicious qualities and ultimately attain 'extreme happiness' and spiritual advancement.
