Vijanamayakosha – The Witness Body 

The witness body is also invisible to the naked eye, and is the part of yourself that is pure consciousness, this is the seat of wisdom. This is the part of your body that recognizes that you see a cup, and you are not a cup, or more relevant to our topic of couple ship, ‘I realize that she/he is having an angry emotion, yet I distinguish also that she/he is not a angry being/person.’

The recognition of what is temporary and what is permanent.
