Why does the Satcharitra argue that life on Earth is more valuable than a place in heaven?

The Shri Sai Satcharitra, in Chapter 37, presents a compelling argument for the profound importance of the earth-world over a heavenly abode. It critiques the desire for heaven, describing it as a temporary realm for sensual enjoyment from which one inevitably falls after their merit is exhausted. The text provocatively states that the pleasure of Indra in heaven is of equal weight to that of a donkey in a dung-heap. In contrast, Chapter 37 emphasizes that even a fleeting life on earth holds greater potential, because one who offers every action to God can attain the fearless and permanent state of liberation, which is far superior to temporary celestial pleasures.
