What is the 'feast' metaphor used in Chapter 49, and what does it reveal about the author's purpose?

In Chapter 49, the author uses a 'feast' metaphor to explain his motivation for sharing Sai's stories. He reflects that a sweet delicacy, while wonderful, loses its sweetness and becomes bland if not shared with friends and virtuous people. Similarly, he feels that the bliss of spiritual realization (the 'self-essence') doubles when it is shared with a 'circle of listeners.' This thought, he says, took root in his soul and led him to mature this "culinary arrangement of essence," which is the Sai Satcharitra itself. This metaphor reveals his compassionate desire to not enjoy the spiritual bliss alone but to share the feast of Sai's stories with all devotees.
