"The honi is a Polynesian greeting in which two people greet each other by pressing noses and inhaling at the same time. This is a very honorific as this represents the exchange of ha--the breath of life, and mana--spiritual power between two people. This act and the concepts behind it are very unusual to western audiences and care should be taken to explain the spirituality and sacredness of this simple act of greeting."
