Can you provide a summary of the main themes discussed in Chapter 40 of the Shri Sai Satcharitra?

Chapter 40 of the Shri Sai Satcharitra opens with salutations and praises Shri Sai Samarth for his ability to fulfill both worldly desires and supreme spiritual goals. The chapter explains that when a devotee seeks exclusive refuge, Sai dissolves the sense of duality, much like a river merges with the ocean, becoming one. It also introduces the idea that Sai himself is the true author of the Satcharitra, with Hemadpant merely being a puppet dancing to his will. As stated in this chapter, Sai is the 'original stimulator of consciousness' who performs his own story. The chapter concludes by setting the stage for a new story about Sai's omnipresence and his satisfaction with food offered with love.
