The Upanishads - Mandhata Global

When the jiva, asleep under the influence of
beginningless maya, is awakened, it then realizes
birthless, sleepless and dreamless Non-duality.
17
If the phenomenal universe were real, then certainly it
would disappear. The universe of duality which is
cognized is mere illusion (maya); Non-duality alone is
the Supreme Reality.
18
If anyone imagines illusory ideas such as the teacher, the
taught and the scriptures, then they will disappear. These
ideas are for the purpose of instruction. Duality ceases to
exist when Reality is known.
VIII
The same Atman explained before as being endowed
with four quarters is now described from the standpoint
of the syllable AUM. AUM, too, divided into parts, is
viewed from the standpoint of letters. The quarters of
Atman are the same as the letters of AUM and the letters
are the same as the quarters. The letters are A, U and M.
