Why does the Shri Sai Satcharitra argue that life on Earth is more significant than a life in heaven?

Chapter 37 posits that the earth-world holds profound importance, even more so than the world of Brahma or other heavenly abodes. While heaven is often seen as a reward, the text describes it as merely a place for sensual enjoyment, from which a soul inevitably falls once its accumulated merit is exhausted. In contrast, life on earth, though fleeting, provides the unique opportunity for spiritual progress. As the chapter explains, a person who offers every action performed in a single moment to God can attain a place of fearlessness. The text devalues any realm, including heaven, that lacks the remembrance of Lord Narayana, concluding that the earth-world is superior because it is the primary ground for performing actions that lead to liberation.
