Look at a situation, person, object – right now. Notice how you feel about that is based upon how you perceive that situation, person, object.
If there were 10 other people in the room, they would each have a different perception and therefore a different feeling.
That being that case, your own perception is not THE truth, but a DESCRIPTION of reality.
Now, who create this description?
And given that you discover it is you, what other descriptions would serve your purpose more usefully?
And, last but not least, what can you learn about yourself from your current description?
Have a play with this exercise and ponder on the questions given.
