What is the true nature of 'heaven' as described in this chapter, and how is it different from just a pleasant place?

Chapter 37 presents heaven not as a location, but as a divine state of being. It is described as the Vairaj (the Cosmic Being) itself, a state of consciousness free from mental grief, disease, worry, sorrow, hunger, and thirst. In this state, there is no fear of old age or death, and the soul moves about completely fearless. This contrasts sharply with a mere place for sensual enjoyment, as this divine heavenly state is defined by the absence of affliction and the presence of fearlessness and non-duality.
