Why does the Satcharitra argue that life on earth is more important than residing in the world of Brahma or other heavenly realms?

Chapter 37 posits that the earth-world is of profound importance, even more so than heavenly abodes. The text argues that heaven is merely a place for sensual enjoyment, and one inevitably falls from it once their accumulated merit is exhausted. It illustrates this by stating that the pleasure of Indra in his celestial garden is fundamentally no different from that of a donkey in a dung-heap. In contrast, life on earth, however fleeting, provides the ultimate opportunity. A person who offers every action to God can attain a permanent state of fearlessness, making earthly existence more valuable than a long but temporary lifespan in a celestial world devoid of true spiritual practice.
