Image if everything you thought you knew as the truth was actually a lie and everything you believed was a lie is actually the truth.
The only way to develop an open mind is leave everything open to question. Only then will your thought process allow you to see things as they actually are, instead of what you want to see.
Imagine if there’s no truth or untruth to be found, only perception. Therefore, you are only limited by your imagination.
“It is the mark of an educated mind to be able to entertain a thought without accepting it.” ~Aristotle.
