The earth element is seen in Later Summer when the gardens produce their food. The Earth is round and supportive. It's color is yellow. The emotion is sympathy. Caring for oneself or tending to others is the earth energy.
So, the photos are of food and cooking. The shapes are circular and the mood is one of taking care of oneself.
Some people may feel emotional "blows" in the gut. Some are unable to eat or may eat too much. Some do not care for themselves physically, emotionally or spiritually.
