How does Chapter 24 characterize great souls like Sai Baba, and what dual purpose does worshipping him serve?

Chapter 24 characterizes Saints, the righteous, and Great Souls as being 'always pure, stainless, and without blemish,' comparing their nature to a clear and cloudless sky. They are presented as inherently faultless beings. The chapter further explains that worshipping Maharaja Sai serves a dual purpose, benefiting the devotee in both material and spiritual realms. It explicitly states that this devotion achieves 'both worldly interests and the supreme goal (Parmartha).' Therefore, as mentioned in Chapter 24, meditation on one's true self through devotion to Sai is said to bring contentment to the heart and fulfill all aspects of a person's life.
