Mistaken essence is the cause of sorrow/suffering.
There is only God/Brahman/Field/Consciousness.
That is the only essence.
All else that is experienced is the play of this singular essence.
So no part of what is seen is essence.
The mistake is to mistake any part of this play to be essence.
It is like gold that is continuously being remodeled and smelted.
Here gold is the essence, and all of the ornaments made with it are subject to change.
So no ornament-form is essence.
Similarly no form in existence is essence.
Essence is formless and quality-less,
And it is not graspable as an object.
One can only be it and experience it directly.
Another analogy would be a VR game,
Where only the “hardware/software/power” are real.
The rest of experience is just the play-out of those 3 as the flow of time.
This is analogous to our essence play as the BME (Body, Mind, Energy) process in time.
No thing is real, and no thing exists.
Only god/brahman/field/consciousness exists.
The evolution process is the play/dream of this field,
And our individual experience is like a figment of this evolution process.
