Truth is the pattern of how things work.
What is true has always been true.
There is truth and everything else that is not true. The difference is only truth is eternal.
Truth is realized through our understanding, but our understanding is not limited to truth. As such, truth can only be found inside you.
Consider your opinion, which changes as you learn new information. The quality of your opinion is a function of its proximity to truth. Once you learn truth your opinion evolves into knowledge.
Knowledge is power because it serves as a breadcrumb to remind you who you are.
Wisdom occurs once you remember.
