What is the relationship between surrendering at the Guru's feet and achieving spiritual realization, as described in Chapter 49?

Chapter 49 posits a direct and essential relationship between surrender and spiritual realization. The text explicitly states, "Without surrendering at the Sadguru’s feet, the true form does not come to hand." This indicates that self-realization is not attainable through personal effort or intellectual pride alone. It is achieved through the Guru's grace, for which one must pray. Saints are described as the form of Shri Hari, and developing love for the Guru's feet is called our "only true wealth." Therefore, complete surrender, devoid of ego and the arrogance of knowledge, is presented as the prerequisite for receiving the Guru's grace and comprehending the true form.
