The heart is the five elements of the heart, and the color is influenced by them. The five elements are born and die, and they are changeable. Ascending according to the truth is like a wave in water. Water and waves are different, and the mind of the five elements and the wisdom of life are also different. Generally speaking, the thinking and behavior we think are all within the scope of thinking and understanding of the five colors, and they are all illusions caused by the wisdom of nature. What you think is that there is no heart, only behavior does not exist. Even unconscious and insensitive behaviors that do not pass through the brain are reflected by inner wrong ideas, but these ideas are not easy to detect and are extremely subtle. In the same way, only you have the heart and no behavior, which is the role of thinking.
