What are the 'nooses of death' according to Chapter 37, and what is the true nature of the 'heavenly world' one can attain?

Chapter 37 of the Shri Sai Satcharitra explains that what we call 'death' is simply a transition from the manifest state back into the unmanifest. The true obstacles, or 'nooses of death,' are identified as unrighteousness (Adharma), ignorance, anger, and hatred. The text states that one who successfully crosses these obstacles enters the heavenly world. This heaven is not merely a physical place but is described as the Vairaj (the Cosmic Being) itself. It is a state of being, the Virat (Cosmic) Self-form, which is free from mental grief, disease, worry, sorrow, hunger, thirst, and the fear of old age or death. In this divine state, the soul moves about completely fearless, devoid of the duality of 'do's and don'ts'.
