Imam Khomeini explains through his theological works that ou should know that with His Wisdom and Authority, God Almighty has created certain powers and faculties in the invisible world of the inner self. They are of enormous benefits for us.
Here we shall mention three of them: they are, al-quwwah al-wahmiyyah-the power of invention or imagination, al-quwwah al-ghadabiyyah-the power of passion or anger, and al-quwwah al-shahwiyyah-the power of lust or sensuality.
Each of these powers is of great benefit to the mankind, like the preservation of the human individual and species, advancement of human interests in this world as well as in the Hereafter, of which religious scholars have given elaborate accounts and I need not repeat them.
What is essential to state here is that these three powers are the source and origin of all virtuous and vicious deeds, and the source of all invisible and sublime forms.
