According to the teachings in the provided text, how does the act of giving help one overcome the 'three gates of hell'?

Chapter 14 explains that the act of giving is a simple remedy planned by the Guru to help a disciple overcome major spiritual obstacles. These obstacles are identified by quoting the Bhagavad Gita, which names "Lust, anger, and greed" as the "three gates of hell, destructive to the self." The text posits that victory over these faults is very difficult. Sai Baba, in his mercy, instituted the practice of asking for Dakshina to help devotees achieve this victory. By encouraging charity ("Dana"), he provided a practical method to combat greed directly and, by extension, the associated faults of lust and anger, thus guiding the devotee away from these destructive paths and toward self-progress.
