When we look within, when we question ourselves, getting a true answer shouldn't be the point. Life is not an examination. It is a series of perceptions followed by choices of action.
The point of questioning ourselves, of self-examination, should be discerning the best action - the best response to our circumstances - and acting accordingly, with a clear mind, clean conscience, and open heart.
Then we should assess our results and, having learned something, repeat the process.
