Mind, this mind, is something like a body, a location in which experiencing from the point of view of subjectivity, is concretised and specified. In this sense body is wholly inside of mind, but what is mind inside of? Mind is as objective as thoughts, as the thoughts which fill it and cannot be the source of experiencing. You can imagine leaving it behind or returning to it, the thinking being and its works, an aspect of the world, of the care for the world.
