According to Chapter 23, what is the root cause of human suffering and what is the only way to overcome it?

Chapter 23 of the Sai Satcharitra explains that the soul's true nature is Existence-Consciousness-Bliss (Sacchidananda), but it forgets this truth by being deluded by Maya. This delusion causes the soul to identify with the body, leading to pride and the false idea that "I am the doer, I am the enjoyer." This mindset results in distress from a succession of calamities. The chapter firmly states that the one and only way to calm these calamities and escape this cycle is through "loving devotion (Bhakti Yoga) at the feet of the Guru."
