According to Chapter 37, why is building a spiritual community on Earth more valuable than aspiring for a heavenly realm?

Chapter 37 presents a powerful argument for the profound importance of the earth-world over a temporary heaven. It states that one should not desire heaven if it "lacks the remembrance of Lord Narayana." The text explains that heaven is a place of enjoyment from which one falls after their merit is exhausted. In contrast, the earth-world, despite its fleeting nature, is of "profound importance." As Chapter 37 clarifies, "Though life is fleeting, he who offers every action performed in a moment to God attains the place of fearlessness." Therefore, building a community on Earth focused on devotion, service, and the narration of divine stories is a far more significant endeavor than seeking a transient heavenly reward.
