Based on the teachings in Chapter 10, what are the comprehensive spiritual benefits a devotee receives by serving a Sadguru like Sai Baba?

Chapter 10 outlines several profound spiritual benefits for those who serve the Sadguru with devotion and faith. It states that by simply remembering the Guru with a loving heart, the knot of birth and death is untied. By placing faith in His feet, one's destiny can be changed. The service of the Sadguru destroys the cycle of worldly existence (Samsara) and helps one overcome physical, mental, and divine miseries. Furthermore, as described in Chapter 10, the Guru's sight can break the knots of the heart, eliminate attachment to sense objects, and destroy both accumulated (Sanchit) and current (Kriyaman) karmas, ultimately leading to liberation (Moksha) characterized by bliss.
