Just as...
Just as, if the relation between the existence of man with the air, light, water and nourishment were cut off, man would no longer survive. He would no longer be able to prepare the ground for the appearance of other men or other phenomena.
From the combination of these two premises it may be concluded that the design of this cosmos, which includes a collection of uncountable phenomena of the past, present and future, is the creation of a single Creator, and under the wise control of a single Lord. For if there were one or more other creators, there would be no relation among them, and no single design would be decreed by them.
Rather, every creature would be brought about by its own creator, and would grow up with the help of other creatures of that same creator. In conclusion, numerous and independent designs would be brought about, and no relations would hold among them, while the present design of the cosmos is a single and interconnected design the connections among whose phenomena are observed.
Finally, the point must be noted that creation and lordship are inseparable, and the nurture and control of a single existent is not separate from its creation and the creation of the things it needs. For example, providing for man is not something separate from creating his digestive system, the creation of nourishment and a livable environment. In other words, these kinds of concepts are abstracted from the relations between creatures and have no instances other than their creation.
Therefore, by proving unity in [the act of] creation, Unity in controlling affairs and other aspects of lordship are established.
Unity in the Emanation of Existence Likewise, another meaning of Unity is the restriction of independent influence and the emanation of existence to the sacred divine essence, for which there is much evidence in the verses of the Qur’ān and narrations from the Prophet ( ṣ ) and Imams ( ‘a ), and this is established by attending to the demonstration which is formulated on the basis of the principles of transcendent theosophy for the Unity of creation and lordship.
However, some misunderstandings exist in this area which must be attended to in order to keep from going to extremes. On the one hand, a group of theologians (Ash‘arites) deny that intermediate causes have any efficacy at all, on the basis of the literal meaning of a group of verses of the Qur’ān and narrations from the Prophet ( ṣ ).
