Holy Trinity

Known as the "Trefoil", "Holy Trinity" and "Trinia". Recognized as the "trefoil" or "holy trinity" it symbolizes the union of the Father, the Son, and the Holy Spirt and as "Trinia" it represents the union of "mind, body, spirit" or "life, death, and rebirth" but I can't tell you what religious sects use it or much else, for that matter. . . it just a symbol that sends chills up and down my spine when I see it. . .
