Parametric,
Actually I would say that your statement requires some clarification. Apparent reality, our experience of the physical world, can be thought of as a product of our biological existence, meaning that apparent reality is our response/reaction to ultimate reality. The world of our experience is precisely that which is call apparent reality---its an interpretation rather than a first order creation. Your saying that that which is self-contained is one thing or one entity, when in fact all living things are all open systems thus not qualifying for your defination of one thing or an entity. Even with the inanimate world there is no real example of a closed system, just systems in greater and greater degrees of isolation, never fully close to the effects of its environment. Even the earth is an open system, open to the cosmos, and just perhaps the cosmos is an open system. One thing is assured us, we are all a part of something larger than ourselves. You might say that reality is itself contained in a sense, for all meaning/s belong to the subject and never the object/physical world, and that meaning is the illusion of apparent reality. Accordding to modern science, ultimate reality is not a place of things..I have tried to come a little in your direct but realized that no, even reality cannot be said to be contained in the subject, for as Schopenhaure reminds us, "Subject and object stand or fall together", in essence, they can never be considered separately consider.
