The first part of the Karika is practically a metrical paraphrase of the Mandukya Upanishad. Peculiar to it is the statement that the world is not an illusion or a development in any sense, but the very nature or essence (svabhava) of Brahma, just as the rays, which are all the same (i.e. light), are not different from the sun. The remainder of the poem is independent of the Upanishad and goes far beyond its doctrines. The second part has the special title of Vaitathya or the "Falseness" of the doctrine of reality. Just as a rope is in the dark mistaken for a snake, so the Atman in the darkness of ignorance is mistaken for the world. Every attempt to imagine the Atman under empirical forms is futile, for every one's idea of it is dependent on his experience of the world. The third part is entitled Advaita, "Non-duality." The identity of the Supreme Soul (Atman) with the individual soul (jiva) is illustrated by comparison with space, and that part of it which is contained in a jar. Arguing against the theory of genesis and plurality, the poet lays down the axiom that nothing can become different from its own nature. The production of the existent (sato janma) is impossible, for that would be produced which already exists. The production of the non-existent (asato janma) is also impossible, for the non-existent is never produced, any more than the son of a barren woman. The last part is entitled Alata-çanti, or "Extinction of the firebrand (circle)," so called from an ingenious comparison made to explain how plurality and genesis seem to exist in the world. If a stick which is glowing at one end is waved about, fiery lines or circles are produced without anything being added to or issuing from the single burning point. The fiery line or circle exists only in the consciousness (vijnana). So, too, the many phenomena of the world are merely the vibrations of the consciousness, which is one.
