According to the teachings, why is life on Earth considered more valuable than attaining a place in heaven?

Chapter 37 explains that the earth-world holds profound importance, even more so than the world of Brahma or a conventional heaven. The primary reason is that heavenly abodes are merely places for temporary sensual enjoyment, and one inevitably falls from them once their accumulated merit is exhausted. In contrast, the earth-world, though life may be fleeting, offers a unique opportunity. As the chapter states, a person who offers every action performed in even a single moment to God can attain the place of fearlessness. This makes life on earth a more valuable and potent ground for achieving ultimate liberation than a temporary stay in a heavenly realm.
