A "belief" is a mental construct that is not required to be connected to reality.
The mind can believe anything about anything.
It takes self observation and introspection to discern whether what you are using to think with (your thoughtware) is a belief or not.
Ignoring this distinction is like not checking to see if the book you are reading is fiction or nonfiction.
A belief does not require you to look around inside of yourself at your internal reality
(for example, at your level of unconscious fear that is being covered up by the belief),
or to look around outside of yourself at external reality
(for example, at how the current level of methane in the atmosphere (1875 ppb) equates to a global temperature of +16 degrees Centigrade higher than what has been average over the past 800,000 years).
Where did you get your beliefs?
Why do you have them?
What if you are finished with your beliefs, in the same way that a butterfly is finished with its cocoon as it flies into the world as an adult?
How can you do that?
