Spirituality and religiosity may be the most important basic elements in the life of the Hopi people. All the other phenomena that we can then call the culture of this people develop first. The spiritual dimensions of the Hopi are found above all in their basic attitude to life, to creation and to reality. It is determined by love and humility for all living things and the insight that we humans are subordinate to the laws of life in the great cycle of creation, yet we still have sacred tasks for the maintenance of balance and harmony in the universe.

Nature is pervaded by many different beings and spirits. Maintaining contact and friendship with them, worshipping them and also asking them for protection and help covers a large part of the very extensive ceremonial life of the Hopi. These ceremonies are firmly connected with daily life, indeed they are an integral part of life itself. The year circle of the Hopi includes nine great ceremonies constituted according to the phase of the moon and solstices. Many of the ceremonies try to maintain or improve harmony with nature, but also include requests for fertility and rain. Every year the ritual dances renew the life patterns and the connection that the Hopi people have with their country, thus with Mother Earth. These ceremonies are held by different clans, who are also responsible for a correct and unchanged form of the ritual. The ceremonies are performed in the so-called "Kiva", an underground, round ceremonial space, which is connected to the world of heaven through a breakthrough in the ceiling. The connection of mother and father, the always-born rebirth of man from mother is to be symbolized here and furthermore the transition into different levels of consciousness and worlds is symbolically represented and introduced by it. In addition to the ceremonial festivals, the Hopi build and maintain sacred shrines in special traditional sacred places in their country. Fixed prayers and rituals at these places also have the task of restoring the balance again and again and thereby protecting the earth from destruction and doom. Thus there is a constant give and take between men and the forces of creation, which is only possible through a humble classification into these cycles.

The worship of the ancestors and the traditional preservation of the knowledge of the own roots and the own history have a very high value in the life of the Hopi. The initiation into this very complicated and filling spiritual life of the Hopi begins at a very early age and is introduced to the children in early infancy through the narration of myths and legends of the tribe and through the use of initiation figures and dolls (katchinas, see section art). The adoption and correct execution of rituals and ceremonies create certain ceremonial hierarchies and orders in the clans, into which every tribal member respectfully fits. An advancement in this hierarchy is regarded as a high honour. The spiritual tasks and rituals form the basis for all actions and movements in daily life.

Mother Earth as the everlasting and giving breadwinner of the tribe and Father Sky, represented above all in the great protective spirit of Massau, are the two great forces in whose hands the Hopi people are carried and protected as their children. They deserve the greatest honor and love in this spiritual system.
