Can you summarize the main themes and teachings presented in Chapter 38 of the Sai Satcharitra?

Chapter 38 of the Sai Satcharitra begins with a series of reverent invocations and salutations to Sai Baba, praising him as the 'King of Gurus' and the 'Destroyer of duality.' The chapter's primary focus then shifts to extolling the supreme virtue of food donation (Annadan). As explained in the text, while previous ages like Krita and Treta prioritized penance and knowledge respectively, the current Kali age emphasizes charity. The chapter argues that food is the form of the Supreme Reality (Para-Brahman) and that donating food is the foremost among all righteous deeds. It also serves as a narrative bridge, mentioning that the previous chapter discussed the Chavadi and this one will introduce the story of the Handi (cooking pot).
