The insight to the most important question in your life lies below. First, observe the symbols and images in your tarot card, then slowly take in the wisdom in your reading.
Justice is not about punishment, good, bad, right or wrong. It is about adjustment. The sword suggests that sometimes this won't be pleasant.
