Beyond the rules for leaving Shirdi, what other significant spiritual teachings are introduced at the beginning of Chapter 9?

The introductory verses of Chapter 9 reveal profound spiritual teachings beyond travel instructions. It explains that Sai Baba's lifelong habit of begging for food was not for himself, but for the welfare of his devotees and for the removal of their sins, including the 'Panchasuna'. Furthermore, the chapter impresses upon the reader the omnipresence of the divine, stating that from Brahma down to the smallest inanimate object, Sai pervades everything. This was to help devotees understand that God resides in all beings, a key spiritual insight that Baba mercifully shared.
