Does the book describe the philosophy of Rumi regarding undivided devotion?

While the name Rumi does not appear in the provided excerpts, Sai Baba strongly emphasizes the principle of undivided devotion. Chapter 19 draws a direct parallel to the Bhagavad Gita's secret, stating, "'Those who think of Me with undivided attention'—this is the secret of the Bhagavad Gita; Govinda provides the well-being and security (Yogakshema) of those who are thus constantly united." This passage from Chapter 19 confirms that surrendering with a focused and undivided heart is a core tenet, and Baba assures that He takes care of all the needs of such a devotee.
