Can you please deeply explain to me what is Al quwwah Al wahmiyyah?

Basically it is the power or illusion/imagination. The human mind has been endowed with the power to imagine either physical objects or abstract ideas. This power allows us to mentally examine the fine details if everything. Now this power must always be guided by the power of the intellect. The intellect shows us right from wrong, and allows to use all out powers for the right cause. The Qowa Wahmiya, if not controlled properly, can cause destruction and explode one’s desires.
