The heart is an eternal, ageless symbol of love and romance, the embodiment of human vitality. Courage, friendship, love, unity, the source of life, sometimes even pain and suffering — all of these are also embodied in this ancient and popular symbol. According to legend, the shape of the symbolic heart is a pair of swans swimming toward each other, which form a heart shape when they touch. Swans are a symbol of love, loyalty and devotion. You can give such a symbol of love to someone you love sincerely and for whom you wish to do good, as well as wishing them prosperity.
