Based on the teachings, what is the root cause of human distress, and what simple practice is suggested for attaining peace?

Chapter 23 teaches that the root cause of human distress is the soul's delusion by Maya, which makes it forget its true nature of Existence-Consciousness-Bliss and instead identify with the physical body. This mistaken identity leads to pride, a sense of being the "doer," and a succession of calamities with no apparent escape. The text offers a powerful remedy for this condition. It states that hearing the stories of saints, like those of Sai Baba, with faith and devotion is a direct way to calm calamities such as sorrow and delusion. This practice helps the devotee to quickly attain peace and contentment, as it resolves doubts and fosters true devotion (Sadbhava) in the heart.
