Triquetra. Celtic talisman, it symbolizes life, death and rebirth; and the three forces of the universe: earth, water and fire. It represents the triple goddess (maiden, mother, and elder); the equality, eternity and indivisibility. The Whole has three levels: Physical, Mental, and Spiritual. The Circle of the Triquetra represents the eternity, and connects the three levels, joining them in only one. With the conversion to Christianity of the Celtic culture, this symbol acquired the meaning of the Trinity: the Father, the Son and the Holy Spirit, and as in the Celtic meaning, the circle represents the eternity.
Celtic cross, symbol of worship and protection. It connects the archaic circle of the mandala, with the Christian cross, i.e. combines the pagan rites with the new religion. It is a symbol of civilization, privilege and intelligence. It protects us against any damage, especially against forms of oppression
