Why does the text argue that the earth-world is more important than heaven, even if life here is short?

Chapter 37 makes a compelling case for the profound importance of the earth-world over the world of Brahma or heaven. It argues that heavenly abodes are merely places for sensual enjoyment, from which one inevitably falls after their accumulated merit is exhausted. The text provocatively states that the pleasure experienced by Indra in heaven is of the same quality as a donkey wallowing in a dung-heap. In contrast, the earth-world, despite its fleeting nature, offers a unique opportunity for spiritual liberation. As explained in Chapter 37, even a life that is just for a moment is superior if every action performed within it is offered to God, as this leads to the 'place of fearlessness.' This highlights the Satcharitra's emphasis on karma yoga and devotion in this very life as the supreme path, rather than aspiring for temporary celestial rewards.
