If the mind is not liberated, you are mindful that ‘the mind is not liberated’. Less obvious is how we can consider the mind in the mind. What is the nature of the mind?

The next layer in is the layer of central processing (sometimes called the mind sphere) and is located at the centre of the sphere of sensory registration. The innermost sphere is the sphere of cogni- tion (sometimes called the sphere of awareness) and is lo- cated at the centre of the sphere of central processing. Our faculties of perception, sensory registration, central processing and cognition can be projected instantaneously to anywhere in the world. In fact what we do when we project our mind is to project our subtle body — something which can be clearly seen by those who have already attained Dhammakāya. If we have attained Dhammakāya we will realize at any moment what our subtle body is doing and we will be able to recognize the owner of the subtle body by its appearance.
