How does the scripture differentiate between the heavenly state and worldly suffering? What is the true nature of heaven?

Chapter 37 of the Shri Sai Satcharitra presents a profound view of heaven, contrasting it with worldly fears. It describes heaven not as a physical place for sensual enjoyment but as the Vairaj (the Cosmic Being) itself—a state of being. This divine heavenly state is characterized by the complete absence of mental grief, disease, worry, sorrow, hunger, thirst, and the fear of old age or death. It is a state free from the duality of 'do's and don'ts,' where the soul can move about fearlessly. This is contrasted with the cycle of worldly existence, which is driven by the mistaken belief that we are separate from Parabrahman.
