According to Chapter 52, what is the root cause of human suffering and the cycle of birth and death, and what is the prescribed solution?

Chapter 52 identifies the fundamental cause of suffering and the cycle of birth and death as 'false knowledge' or delusion. It defines this delusion as the pride of the Self in that which is not the Self—essentially, a lack of focus on our true spiritual nature and an incorrect identification with the temporary body and ego. The chapter states that this error is the root of all calamities. The prescribed solution, as outlined in Chapter 52, is to connect with the feet of the Guru through continuous remembrance and devotion. By constantly keeping one's mind occupied with Sai Baba through all states of consciousness—waking, dreaming, and deep sleep—one can find liberation from worldly attachment.
