God and His energy are inseparable; the concept of the power and the powerful comes to the forefront once again, and it is so apt while describing the significance of the Shri Yantra. The geometrical pattern of this Yantra is explanation in itself. Its design is based on intersection of nine triangles. Four of these triangles point upward and five downward. The four upward pointing triangles are the Shiva triangle (Male or Yang forces) and five downward pointing triangles are Shakti or Durga triangles (female or Yin forces). A combination of these nine triangles makes Shri Yantra the most dynamic of all Yantras, and the complete symbol of the power and the powerful.

The ancient scriptures of Brihadaranyaka Upanishad says

“He was alone,
he did not enjoy,
one alone does not enjoy,
He desired a second,
and became like a man and woman in close embrace.”

This is the concept of the Shri Yantra, a uniting and harmonizing device where the male and female energy is taken into the higher level of desire and union.
It is a device that protects man – woman relationship among many other things and dates back to the concept of human’s becoming a social animal rather than just living creature.
