Maharishi teaches that the Vedas are sounds and vibrations that manifest the entire relative field; that manifest the infinity of Universes of all of Creation.

The Vedas are the Laws of Nature.

They are the first sounds and vibrations to emerge from Wholeness, from the Field of the Absolute.

Upanishad, Aranyak and Brahmana are the Vedas that manifest the process of meditation in the human physiology.

Upanishad is the ascending tracts of the central nervous system, the transcending of the relative field.

Aranyak is the fasiculi proprii, the stirring of the Crown Chakra when your Self is left by ItSelf to experience ItSelf.

And Brahmana is the descending tracts of the central nervous system, the structuring of the relative field when you return to consciousness of waking, dreaming or sleeping.

Meditating, transcending the relative field, being Pure Consciousness, and returning to consciousness of the relative field, this is Upanishad, Aranyak, Brahmana.

When you transcend regularly and repeatedly, you become established in your Self, established in Pure Consciousness.

You hold two states of Consciousness at the same time:

Consciousness of your Self along with consciousness of the relative field.

This is the first stage of Enlightenment:

Upanishad, Aranyak and Brahmana all experienced simultaneously and eternally.

This is why you are here.
