How does Chapter 49 compare devotion to the Guru with other spiritual practices?

Chapter 49 of the Sai Satcharitra places devotion to the Guru above all other spiritual disciplines. The text presents a hierarchy of practices, stating that while penance is greater than pilgrimages, vows, sacrifices, or charity, and the singing of Hari's name is greater still, the "meditation on one's own Guru is the greatest of all." For devotees, Sai is presented as the sole object of meditation and worship, their "secret treasure." The author emphasizes that love for the Guru's feet is the "only true wealth" and that surrendering to the Sadguru is the only way to grasp the true form, as saints are themselves the form of Shri Hari.
