According to the Shri Sai Satcharitra, what is Sai Baba's perspective on heaven, and why is life on Earth considered more valuable?

Chapter 37 of the Shri Sai Satcharitra presents a nuanced view on the concept of heaven. It describes the heavenly home as merely a place for temporary sensual enjoyment, from which one inevitably falls after their accumulated merit is exhausted. The text provocatively states there's little difference in the nature of sensual pleasure enjoyed by Indra in his celestial garden and a donkey in a dung-heap. In contrast, the earth-world is deemed of profound importance because, though life may be fleeting, it offers the opportunity to dedicate one's actions to God. As Chapter 37 explains, a person who offers every action to God, even for a moment, can attain a state of fearlessness. This makes our earthly existence a more valuable ground for true spiritual progress than a temporary heavenly reward.
