At the route of all thinking is a desire to understand the nature of consciousness

Humans cannot grasp the concept and mechanics of domains other than their own

4 dimensional surroundings, (i.e Length/ Width/ Depth & time.)

 

And yet we have an awareness of thought(s). 

Thought(s) most definitely do exist but  they do not have any mass or location.

So perhaps we do have an insight into other realms.

 

If there is a connection between thoughts and energy as there is between energy and mass

and mass and time - then Beings of both pure energy and pure though are feasible.
