This superior nature can be understood as the living force, which is present in the bodies of all living creatures. The body itself is composed of inferior nature, matter, but it is the superior nature that is moving the body. The symptom of that superior nature is consciousness. Thus in the spiritual world, where everything is composed of the superior nature, everything is conscious. In the material world there are inanimate objects that are not conscious, but in the spiritual world nothing is inanimate. There a table is conscious, the land is conscious, the trees are conscious—everything is conscious.
It is not possible to imagine how far this material manifestation extends. In the material world everything is calculated by imagination or by some imperfect method, but the Vedic literatures give real information of what lies beyond the material universe. Since it is not possible to obtain information of anything beyond this material nature by experimental means, those who believe only in experimental knowledge may doubt the Vedic conclusions, for such people cannot even calculate how far this universe extends, nor can they reach far into the universe itself. That which is beyond our power of conception is called acintya, inconceivable. It is useless to argue or speculate about the inconceivable. If something is truly inconceivable, it is not subject to speculation or experimentation. Our energy is limited, and our sense perception is limited; therefore we must rely on the Vedic conclusions regarding that subject matter which is inconceivable. Knowledge of the superior nature must simply be accepted without argument. How is it possible to argue about something to which we have no access? The method for understanding transcendental subject matter is given by Lord Kṛṣṇa Himself in the Bhagavad-gītā, where Kṛṣṇa tells Arjuna at the beginning of the Fourth Chapter:
