1. (noun) spirit, soul - spirit of a person which exists beyond death. It is the non-physical spirit, distinct from the body and the mauri. To some, the wairua resides in the heart or mind of someone while others believe it is part of the whole person and is not located at any particular part of the body. The wairua begins its existence when the eyes form in the foetus and is immortal. While alive a person's wairua can be affected by mākutu through karakia. Tohunga can damage wairua and also protect the wairua against harm. The wairua of a miscarriage or abortion can become a type of guardian for the family or may be used by tohunga for less beneficial purposes. Some believe that all animate and inanimate things have a whakapapa and a wairua. Some believe that atua Māori, or Io-matua-kore, can instill wairua into something. Tohunga, the agents of the atua, are able to activate or instil a wairua into something, such as a new wharenui, through karakia. During life, the wairua may leave the body for brief periods during dreams. The wairua has the power to warn the individual of impending danger through visions and dreams. On death the wairua becomes tapu. It is believed to remain with or near the body and speeches are addressed to the person and the wairua of that person encouraging it on its way to Te Pō. Eventually the wairua departs to join other wairua in Te Pō, the world of the departed spirits, or to Hawaiki, the ancestral homeland. The spirit travels to Te Reinga where it descends to Te Pō. Wairua of the dead that linger on earth are called kēhua. During kawe mate, or hari mate, hura kōhatu and other important occasions the wairua is summoned to return to the marae.

1. (noun) baskets of knowledge - these are the three baskets of knowledge obtained for mankind by the god Tāne, known primarily as the god of the forests and all that dwells within them. To acquire the baskets of knowledge, Tāne had to ascend to the twelfth heaven, to Te Toi-o-ngā-rangi, and there be ushered into the presence of the Supreme God, of Io-matua-kore himself, to make his request. The request was granted and hence the knowledge we now have in our possession and at our disposal. Tāne had to reconnoitre and negotiate eleven other heavens before ascending to the twelfth and there receive the knowledge he sought. The three baskets of knowledge are usually called te kete tuauri, te kete tuatea and te kete aronui.
