In Attar's Mosibat Nameh, the tale of the broken millstone serves as a spiritual allegory for finding peace through the breaking of worldly attachments and the ego. While the disciples mourn the loss of their wealth and physical effort, the Sheikh realizes that the stone's breaking is a blessing that frees it from its endless, dizzying rotation. This symbols how the soul, trapped in the restless and repetitive search within the material world, can only find eternal tranquility when its worldly form and desires are shattered.
