Sunlight is the illuminator, the प्रकाशकः. It is
Formless - निराकारः
Division less - निर्विकल्पः
Pure, can't be polluted -निर्मलः, शुद्धं
Free of boundaries, infinite in space and time - निस्सीमः, अनन्तः
Uninvolved, independent of what is illumined in it's presence असङ्गः, स्वतन्त्रः
Changless - निर्विकारः
The light of consciousness that shines as "I" is like the sunlight. It is an illuminator ...in it's presence alone every thought gets revealed, the world is revealed. It pervades all that it reveals and yet is independent of what is illumined/ revealed in it's presence. Being independent it is untainted by whatever is revealed in it's presence. It is formless, all pervading and free of all divisions. It is changelessly ever-presence. Light reveals the room ...when the room is dirty, light does not get dirty. Light is changeless. So too is the light of consciousness.
The light does not do an action of illuminating. Action requires motion and motion requires limitation. If we take example of the hand ...motion is possible for the hand because hand is limited in space. Therefore it can move. Whereas light which is all pervading in this room, cannot move. It is akarta. In it's presence everything gets illumined. So too in the presence of the light of all-pervading consciousness, all actions are revealed .... consciousness is changeless, motionless. It cannot do action. It never does any action.
You can meditate thus.
