9.  Atharba Veda :

    Maandukyo  Upanishat 

AUM  &  4 stages of Consciousness

Mind  i) Out ward  ii)  In-ward  iii)  eliminated state

          a) Vaishwanor   b) Toijaso  c)Projna  d)Turyo or  Super- 

             conscious state.

AUM   stands for  non-dual or supreme reality.

Brahman is all and SELF is Brahman. Brahman has four stages of Consciousness:

I. Vaishwanor  - in this one lives with  all senses turned outward.

II. Taijasa - The dreaming state in which the senses turn 

     inwards with past deeds &  present desires [Dreaming  with

     desires even in waking state]

III.Projna  - Deep sleep ; neither dreams nor desires. Mind is 

     eliminated in this state; yet the sleeper is not Conscious. If 

     he was, it would open the door of abundant joy !

IV.Turyo --Super-conscious state ( beyond all senses and 

     intellect (attainable in Samadhi ).

 ABOUT  AUM :

A = the zone of Vaishwahara:  U= the zone of Taijasa ; 

M= the zone of Prajna.

* [By stilling the Mind one  can attain the true stature.

** Mind 'externalised' is the worldly-man.
