That is the difference. Therefore the jīva-prakṛti is called superior because the jīva has consciousness which is similar to the Lord's. The Lord's is supreme consciousness, however, and one should not claim that the jīva, the living entity, is also supremely conscious. The living being cannot be supremely conscious at any stage of his perfection, and the theory that he can be so is a misleading theory. Conscious he may be, but he is not perfectly or supremely conscious.
The distinction between the jīva and the īśvara will be explained in the Thirteenth Chapter of Bhagavad-gītā. The Lord is kṣetra-jña, conscious, as is the living being, but the living being is conscious of his particular body, whereas the Lord is conscious of all bodies. Because He lives in the heart of every living being, He is conscious of the psychic movements of the particular jīvas. We should not forget this.
