The ancient Vedic scriptures declare that the physical world operates under one fundamental law of maya, the principle of relativity and duality. God, the Sole Life, is an Absolute Unity; He cannot appear as the separate and diverse manifestations of a creation except under a false or unreal veil. That cosmic illusion is maya. Every great scientific discovery of modern times has served as a confirmation of this simple pronouncement of the rishis.

Newton’s Law of Motion is a law of maya: “To every action there is always an equal and contrary reaction; the mutual actions of any two bodies are always equal and oppositely directed.” Action and reaction are thus exactly equal. “To have a single force is impossible. There must be, and always is, a pair of forces equal and opposite.”

Fundamental natural activities all betray their mayic origin. Electricity, for example, is a phenomenon of repulsion and attraction; its electrons and protons are electrical opposites. Another example: the atom or final particle of matter is, like the earth itself, a magnet with positive and negative poles. The entire phenomenal world is under the inexorable sway of polarity; no law of physics, chemistry, or any other science is ever found free from inherent opposite or contrasted principles.

Physical science, then, cannot formulate laws outside of maya, the very texture and structureof creation. Nature herself is maya; natural science must perforce deal with her ineluctable quiddity. In her own domain, she is eternal and inexhaustible; future scientists can do no more than probe one aspect after another of her varied infinitude. Science thus remains in a perpetual flux, unable to reach finality; fit indeed to formulate the laws of an already existing and functioning cosmos, but powerless to detect the Law Framer and Sole Operator. The majestic manifestations of gravitation and electricity have become known, but what gravitation and electricity are, no mortal knoweth.

To surmount maya was the task assigned to the human race by the millennial prophets. To rise above the duality of creation and perceive the unity of the Creator was conceived of as man’s highest goal. Those who cling to the cosmic illusion must accept its essential law of polarity: flow and ebb, rise and fall, day and night, pleasure and pain, good and evil, birth and death. This cyclic pattern assumes a certain anguishing monotony, after man has gone through a few thousand human births; he begins to cast a hopeful eye beyond the compulsions of maya.

To tear the veil of maya is to pierce the secret of creation. The yogi who thus denudes the universe is the only true monotheist. All others are worshiping heathen images. So long as man remains subject to the dualistic delusions of nature, the Janus-faced Maya is his goddess; he cannot know the one true God.

The world illusion, maya, is individually called avidya, literally, “not-knowledge,” ignorance, delusion. Maya or avidya can never be destroyed through intellectual conviction or analysis, but solely through attaining the interior state of nirbikalpa samadhi. The Old Testament prophets, and seers of all lands and ages, spoke from that state of consciousness. Ezekiel says (43:1-2): “Afterwards he brought me to the gate, even the gate that looketh toward the east: and, behold, the glory of the God of Israel came from the way of the east: and his voice was like a noise of many waters: and the earth shined with his glory.” Through the divine eye in the forehead (east), the yogi sails his consciousness into omnipresence, hearing the Word or Aum, divine sound of many waters or vibrations which is the sole reality of creation.The ancient Vedic scriptures declare that the physical world operates under one fundamental law of maya, the principle of relativity and duality.
