What is the philosophical explanation of the soul's delusion and the path to liberation offered in Chapter 23?

Chapter 23 explains that the soul is, in reality, beyond the three gunas (qualities) and its true nature is Existence-Consciousness-Bliss (Sacchidananda). However, it becomes deluded by Maya, causing it to forget this true nature and identify with the physical body. This mistaken identity leads to the prideful thought of being the "doer" and "enjoyer," which results in a succession of calamities and distress. According to the teachings in Chapter 23, there is a clear path of escape: loving devotion (Bhakti Yoga) at the feet of the Guru is presented as the only way to calm these calamities and guide the soul back to its true state of being.
