Sai Baba's philosophy seems to de-emphasize the pursuit of heaven. Can you explain this perspective using the Satcharitra?

Chapter 37 explains that the pursuit of heaven is misguided because it is merely a place for temporary sensual enjoyment. The text makes a striking comparison, stating that the pleasure Indra experiences in his heavenly garden is of the same quality as that of a donkey wallowing in a dung-heap. It cautions that one inevitably falls from heaven after their merit is exhausted. Therefore, it is far better to value our time in the earth-world, which is described as being of profound importance. Even a momentary life on earth, if every action is offered to God, can lead to the ultimate place of fearlessness, a state superior to any temporary heavenly abode.
