"...while your physical time, or clock time, has no overall basic reality, and is not a primary reality, that runs through various fields or systems, it is nevertheless an electromagnetic reality within your own system, for you have created is on mental terms... if it were a primary reality, you would not escape from it even in the sleeping state. Those realities which are primary you can never escape from. This should give you an idea, for those realities which run through all systems, and which are primaries, are those which exist for you in all conditions of consciousness and under any circumstances."
