There's something called eye accessing cues. This phenomenon proposes that people's eyes look to certain directions for different types of thoughts the person has. • upper left - visual remembering • upper right - visual construction • very left - auditorial remembering • very right - auditorial construction • lower left - auditory digital [don't ask me what that means] • lower right - thoughts of or pertaining to the thinker's body and/or emotions • straight ahead - visual defocused . I'm almost positive that eye accessing cues are a real thing. Something I'm not sure about but conjecture to be true is that all of the cues listed above are reversed in left–handed people.
Actions spoken of, along with one's "manual" dexterity often reflect one's true intent. Bold, light, curved sharply or smooth, "follow through", etc. Etched in one's hand, is the wisdom sought by many. As a precautionary note, "Wisdom is often fleeting".
