Three.

This powerful Celtic symbol dates back to 2500 b.c. It's the oldest known Celtic symbol, and is referred to as a triple spiral, Celtic spiral or the Celtic trilogy.

Some say this symbol represents the 3 stages of life: birth, death and eternity; others see it as land, sea and sky. Pagans view it as a symbol of the triple goddess and believe it represents phases of the moon. Sometimes Christians use the symbol to represent the Father, Son and Holy Ghost. I've also seen it referred to as a sign of female power - especially power through transition and growth.

Besides the "three prongs" and the associated meanings above, this mark also implies movement: action, constantly going forward, learning and spiritual growth.

Today, this shape to me means, simply, moving towards our three: Father, Mother and Child.
