May Day is Lei Day in Hawaii. A HISTORY OF LEI DAY: The lei, known the world over, is a symbol of aloha. Great care is taken in the gathering of the materials to make a lei. After the materials are gathered, they are prepared and then fashioned into a lei. As this is done, the mana (or spirit) of the creator of the lei is sewn or woven into it. Therefore, when you give a lei, you are giving a part of you. Likewise, as you receive a lei, you are receiving a part of the creator of the lei. HAPPY LEI DAY, EVERYONE!
