This cool HAND symbol named Shaka represents the essence of what is the "Aloha Spirit", the coordination of mind and heart within each person. It brings each person to the self, with remote good feelings to others. In the contemplation and presence of the life force, "Aloha", may be used :
"Akahai", meaning kindness to be expressed with tenderness
"Lōkahi", meaning unity, to be expressed with harmony
"ʻOluʻolu" meaning agreeable, to be expressed with pleasantness
"Haʻahaʻa", meaning humility, to be expressed with modesty
"Ahonui", meaning patience, to be expressed with perseverance
