The triangle shares all the 
symbolic significance of the number 3, as a shape, and therefore 
represents the many things that come in groups of three, from the Holy 
Trinity to the triple aspect of the Goddess. Triangles appear in lots of
 different signs and symbols. In ancient times, the triangle was 
considered synonymous with light, and the meanings of the triangle vary 
according to which way up it is. When it sits firmly on its base, then 
it is a masculine, virile symbol, representing fire. The other way up it
 becomes the water element, a chalice shape, emblematic of the feminine 
powers. Balanced on its point in this way the triangle also represents 
the yoni, further underpinning the Goddess aspect. The equilateral 
triangle is a harmonious form, used to indicate the Higher Powers, providing a framework, for example, for the All Seeing Eye of God.
As a symbol of strength, the triangle reinforces the 
corners of the square, both physically and meta-physically. The solid 
shape of the triangle also makes its appearance in yogic positions, for 
example in the Trikona Asana or Triangle Posture.
