Based on this text, what is the path to overcoming the fear of death and achieving the 'divine heavenly state'?

The path to overcoming the fear of death, as outlined in Chapter 37, involves transcending the 'nooses of death,' which are defined as unrighteousness, ignorance, anger, and hatred. The text suggests that he who crosses these entirely enters the heavenly world. This divine state is characterized as being free from duality, worry, illness, and the fear of death. A key element is to overcome the deluded belief that you are separate from Parabrahman. The text emphasizes that the same divine principle pervades all of creation, and realizing this unity leads to a fearless state, which is the true divine heavenly state.
