According to the teachings in Chapter 10, what is considered the best and most effortless spiritual practice?

Chapter 10 presents a simple yet profound spiritual practice (Sadhana) as the best of all means. It advises one to "Always remember with a heart full of love Him who is devoted to the welfare of all people." This act of mere remembrance of the Guru is said to be powerful enough to untie the knot of birth and death. The text emphasizes the accessibility of this path, noting that it costs nothing, requires little effort, and yet yields great fruit. It is positioned as a superior method to intellectual acrobatics or complex rituals, where simple faith in the Guru brings everything, including liberation, easily into one's hands.
