We do have a full grasp of the first mode, which is the substance, i.e., the manifestations of the activities that arise from every essence. These manifest to us the essence that lies within the substance in a comprehensive manner, such that we do not suffer at all from the lack of perception of the essence itself. We do not miss it at all, just as we do not miss a sixth finger on our hands. The perception of the substance, that is, the manifestations of the activities of the essence, is completely sufficient for all our needs and perceptions, both for the perception of our own beings and for the perception of all of existence outside of us.
