Recently some theoretical physicists have begun to recognize that not only does matter consist of energy, but energy consists of consciousness. Others have recognized that physical events change by virtue of being observed, with what is called the Heisenberg Uncertainty Principle. Einstein discussed the relative nature of space and time based on the status of the observer as well.
Sri Aurobindo describes these issues as follows: “It would seem as if Time had no objective reality, but depends on whatever conditions may be established by action of consciousness in its relation to status and motion of being: Time would seem to be purely subjective. But, in fact, Space also would appear by the mutual relation of Mind-space and Matter-Space to be subjective; in other words, both are the original spiritual extensions, but it is rendered by mind in its purity into a subjective mind-field and by sense-mind into an objective field of sense-perception. Subjectivity and objectivity are only two sides of one consciousness, and the cardinal fact is that any given Time or space or any given Time-Space as a whole is a status of being in which there is a movement of the consciousness and force of the being, a movement that creates or manifests events and happenings; it is the relation of the consciousness that sees and the force that formulates the happenings, a relation inherent in the status, which determines the sense of Time and creates our awareness of Time-movement, Time-relation, Time-measure. In its fundamental truth the original status of Time behind all its variations is nothing else than the eternity of the Eternal, just as the fundamental truth of Space, the original sense of its reality, is the infinity of the Infinite.”
The implications of these concepts are just now being pondered by physicists who are beginning to grasp the spiritual Reality of consciousness constituting, creating and manifesting the universe. When we loosen the grip of material consciousness, we can begin to understand how the apparently unbreakable laws of Time and Space are actually relativities that respond to movement in consciousness. And this becomes the key to liberation.
