Aletheia
ἀλήθειαah-LAY-thay-ah
Truth as unconcealment. Not merely accurate statements, but the fundamental orientation toward reality as it actually is, the state of being unhidden.
Modern Application
You practice aletheia when you orient yourself toward what's real rather than what's comfortable. It shows up in honest self-assessment, in refusing to deceive others or yourself, and in the freedom that comes from having nothing to hide. Living in truth is energetically efficient. Deception is overhead that compounds.
