What is the cause of human suffering and what is the prescribed remedy in Chapter 23?

Chapter 23 explains that the soul's true nature is Existence-Consciousness-Bliss (Sacchidananda), but it becomes deluded by Maya. This delusion causes the soul to forget its true self and identify with the physical body, leading to the prideful thought, "I am the doer, I am the enjoyer." This false identification results in a succession of calamities and distress. The chapter posits that the only way to calm these calamities and escape this suffering is through "loving devotion (Bhakti Yoga) at the feet of the Guru."
