The Satcharitra mentions a 'heavenly world.' Does it describe this as a physical place for enjoyment?

No, Chapter 37 clarifies that the heavenly world is not merely a place for sensual enjoyment attained through sacrifices. In fact, it dismisses a heaven where there is no remembrance of the Lord's name. Instead, it defines heaven as a state of being—the Vairaj (the Cosmic Being) itself. This divine heavenly state is characterized as being free from mental grief, disease, sorrow, hunger, thirst, the fear of old age, and the fear of death. It is a state where the soul moves about completely fearless, devoid of the duality of 'do's and don'ts'.
