Based on chapter 23, what is the nature of the human soul and what is the prescribed way to overcome its suffering?

Chapter 23 explains that the soul's true nature is Existence-Consciousness-Bliss (Sacchidananda) and it is beyond the three gunas (qualities). However, it becomes deluded by Maya, causing it to forget its real self and identify with the body. This leads to the prideful thought, "I am the doer, I am the enjoyer," which in turn results in a succession of calamities and distress. The chapter explicitly states that the only way to calm these calamities and escape this cycle of suffering is through loving devotion (Bhakti Yoga) at the feet of the Guru, who can transform the devotee.
