The whole universe is a projection of the mind.

The four principles of Jnana Marga are:

The first principle
------------------------
The whole universe is a projection of the mind. 
Everything you see in this world,
everything that happens in your life is a projection of your mind.
It has no substance, no value.
You are the creation of the universe.

The second principle
----------------------------
We do not prevail.
There is no substance in back of your existence.
You didn't come from anything.
You were never born. You can never die.
You are no thing that you can ever imagine.
And your life as it appears does not exist.

The third principle
------------------------
No thing that exists has an ego.
There is no ego to back anything up.
You have believed all of these years that you have an ego
and that you have to get rid of it.
There is no ego to be gotten rid of.
If there is no ego there is nothing to do.
There is nothing to fear and there is nothing to fight.

The fourth principle
---------------------------
The understanding what self-realization is not.
You can never understand realization.
But you can understand what it is not.
Everything that exists is not.
When everything is gotten rid of, realization appears by itself.
They're in the transcripts.
