What specific belief or mindset does the Satcharitra say keeps a person stuck in the cycle of birth and death?

In Chapter 37, the Shri Sai Satcharitra identifies a specific mindset born of ignorance as the cause for being trapped in the cycle of worldly existence (Samsara). The text states that one who holds the belief "Parabrahman is different from me; I am not that, I am something else" is always subject to death. This perception of difference or separation from the ultimate reality is what perpetuates the eternal cycle where birth is followed by death, and death is followed by rebirth. Overcoming this deluded sense of separation is key to liberation.
