Why is life on Earth considered more valuable than a long life in heaven, according to this text?

Chapter 37 of the Shri Sai Satcharitra argues that the earth-world holds more profound importance than heaven. The primary reason is that one's stay in heaven is temporary; a person falls from it once their accumulated merit is exhausted. In contrast, the earth-world provides a unique opportunity for spiritual progress. The text emphasizes that even if life on earth is fleeting, a person who offers every action to God can attain a place of eternal fearlessness. It questions the use of any place, including the world of Brahma, if it lacks devotees, the stories of Hari and the Guru, and the worship of God, making Earth the superior ground for devotion.
