Reliable Barometer?

From the Morgan Greer Tarot, the Page of Cups; from the Goddesses and Sirens, 'Morgan le Fae:'

          The Page of Cups has an unarmored heart, therefore his life is like a wellspring of fresh emotions. That might be fine (as those emotions can come and pass away quickly), but he is so sensitive that he at times feels like that fish out of water gulping in air. He could use someone more experienced to show him the ropes - not how to shut off his feelings but to recognize they don't always reflect the truth. As Allen Berger states: "I believe it’s important to respect our feelings. No question about it. But we create problems when we give our feelings too much privilege in our lives." Morgan le Fae is a powerful enchantress associated with the Arthurian tales. Though early versions showed her as a healer and protector, later versions cast her as a dark, malevolent power. This change in the telling of the legend was likely due to a Christian push against the pagans. How do you create hate? Through fear. But as the Page will eventually learn, feelings are rarely a reliable barometer for what is real.
