I really enjoyed this article and found it interesting how Native Hawaiian believe the pohaku carry spiritual power.  It is the same in Native American Culture at least in our tribe the Lakota Sioux in fact some medicine mens powers come from such a rock That in some cases choose them.  You never know what type of mana maybe in a certain rock so it is important to be careful in which pohaku may choose you when such things happen it must be taken care with certain ceremonies and medicine men.
