To apprehend an object means to hold or grasp an object. Apprehending an object is not synonymous with perceiving an object. Some minds perceive objects but do not apprehend them. For example our eye awareness apprehending this page perceives an inherently existent page but does not apprehend it. Because it perceives the page to be inherently existent it is a mistaken awareness, but because it does not apprehend an inherently existent page it is not a wrong awareness. Wrong awarenesses not only perceive their wrong objects but also apprehend them.
