How can one achieve true liberation and avoid the cycle of birth and death, according to Sai's teachings in this chapter?

As explained in Chapter 37, the cycle of worldly existence (Samsara), where rebirth follows death, is perpetuated by a key delusion: the belief that one is separate from the Parabrahman. The text states that he who thinks "Parabrahman is different from me; I am not that" is always subject to death. True liberation, therefore, requires overcoming this ignorance and realizing the science of the oneness of Brahman and the Self. One must also cross the metaphorical 'nooses of death,' which are identified as unrighteousness, ignorance, anger, and hatred. By transcending these negative qualities and the illusion of separateness, the soul can move about fearlessly and break free from the eternal cycle of birth and death.
