The dictionary meaning of the word ‘perception’ is to become aware of, to apprehend. That is, you see the cupboard, you have a preconception of it; that is not perception. Is there seeing without preconception?
Only the mind that has no conclusion, such a mind can see. The other cannot. If I have previous knowledge of that cupboard, the mind identifies it as cupboard. To look at that cupboard without the previous accumulation of prejudices or hurts, is to look. If I have previous hurts, memories, pain, pleasure, displeasure, I have not looked.
