What is the concept of 'heaven' as explained in the Shri Sai Satcharitra, and how does it differ from a physical place?

The Shri Sai Satcharitra, in Chapter 37, presents a spiritual and philosophical definition of heaven that is distinct from a physical location. It is described as the Vairaj, or the Cosmic Being itself—a state of being where one beholds the Cosmic Self-form, free from all mental grief. This divine heavenly state is characterized by the absence of disease, worry, sorrow, hunger, thirst, and the fear of old age or death. In this state, the soul moves about completely fearless. It's not a place to be attained after death through rituals but an inner state of consciousness achieved by overcoming the 'nooses of death' like ignorance and hatred.
