What are the primary teachings and warnings for devotees presented in Chapter 9 of the Sai Satcharitra?

Chapter 9 of the Sai Satcharitra delivers several key teachings, primarily centered on the absolute necessity of following Sai Baba's instructions. The chapter explicitly states that a unique characteristic of the Shirdi pilgrimage is that if a devotee departs without Baba's permission, they invite obstacles and trouble. Conversely, it also warns that once permission is given, one must not linger, as staying longer also brings misfortune. The chapter further explains that Baba's practice of begging was for the welfare of devotees, and it reinforces the spiritual concept that Sai is omnipresent, residing in all beings from the highest creator to the smallest inanimate object.
