Whoever undertakes to set himself up as a Judge of Truth and Knowledge is shipwrecked by the laughter of the gods. Albert Einstein
The difference here in knowing Truth and Knowledge is the source of that determination. I believe that would be the word JUDGE. Judging, in my definition, is sorting out with the brain perceived information to make a judgement. I hope I am not guilty of this type of superiority as to think I know when I can only surmise. To surmise is just to make an opinion or conjecture.
When I do have a knowing, it is not from my brain; but from my heart and the emotion that a situation gives me. Not that I have clear understanding, but a hint that all presented is not all there is to the picture/situation/person as really authentic. Or a knowing to follow a certain course of action that the brain hasn’t dictated.
This is also a trust issue that I can winnow out what information from myself or others is a ‘knowing of the brain‘ vs the ‘knowing of the heart.’ Do not disregard lightly information from the heart.
