What does Chapter 23 say about the cause of human suffering and the way to find relief?

According to Chapter 23, the root of human suffering stems from the soul's delusion by Maya. This delusion causes the soul to forget its true, blissful nature of Existence-Consciousness-Bliss (Sacchidananda) and instead identify with the physical body. This mistaken identity leads to pride and the false belief of being the "doer" and "enjoyer," which in turn results in a succession of calamities and distress. The chapter clearly 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 a Guru, who can color the devotee in His own divine hue.
