Pancadasi - Chapter 1 Verse 3

Verse 3:
The objects of knowledge, viz sound , touch etc which are perceived in the waking state are different from each other because of their peculiarities; but the consciousness of these which is different from them, does not differ because of its homeogenity.

My Understanding
Objects of Knowledge.

Objects of knowledge refer to the what the subject sees through the senses or perceive through the senses subjected to his or her own interpretation.The seer is the subject and the seen is the object. Hence the object of knowledge refers to the knowledge about what is perceived through the human senses. According to Plato, objects of Knowledge refers to the idea we carry about a Tree , a dog etc.

Ability to identify different objects, in itself means there is a property or set of properties which uniquely characterizes that object givings its peculiar nature as perceived by the mind through the senses.

Who perceives the senses ? it is the varigated mind with its multitude of its own but who perceives the mind , that is the being or the consciousness . To know that something is always changing, there should be that something which never changes to observe that fact. That is the consciousness of the self which unlike the objects of knowledge doesnt change but remains the chengless observer of the change.
