What are the primary teachings conveyed in Chapter 9 of the Sai Satcharitra?

Chapter 9 of the Sai Satcharitra imparts several crucial teachings for devotees. A central theme is the absolute necessity of obtaining Sai Baba's permission before departing from Shirdi. The text explicitly states that leaving without his consent invites obstacles, while overstaying after receiving permission also leads to trouble. This chapter also explains the spiritual significance of Baba's practice of begging for food, clarifying it was for the welfare of his devotees and the removal of their sins. Furthermore, as mentioned in Chapter 9, a core message is that Sai, representing God, is omnipresent and mercifully impresses upon us that divinity resides in all beings and objects.
