The Shri Yantra is one of the most powerful and important Yantras. By definition the yantra is a geometric design that starts from the centre and is used as an aid to concentration and meditation in certain spiritual traditions. The word “yantra” comes from the Sanskrit roots yan-, yantr- and could mean "tool, support, amulet."

The Shri Yantra is the symbol of Hinduism, which is based on the Hindu philosophy of the Vedas. Initially, yantras were created by ancient mystics and were used only within a narrow circle of the selected few introduced to secret knowledge. The science of yantras was kept in sacred scriptures and was passed from gurus to their followers.
First yantras served to encode the sacred knowledge of the Universe and represent various energies. Later, some yantras were used as powerful amulets. “Shri Yantra” means Instrument for Wealth. It is believed to help in material and spiritual matters. 
The main purpose of yantras is to help one's mind concentrate on it and connect a practitioner to the specific energy contained within this yantra, thus increasing awareness and creating harmony. Yantras are believed to have have the power to expand one's consciousness. 
Typically, yantras are created of various geometric forms; they could be simple or complex. Unlike mandalas, they are abstract, geometric, lacking decorations and monochromatic.  

What is So Special About The Sri Yantra?
The Sri Yantra diagram is formed by 9 triangles that radiate from the central point. These nine triangles are of various sizes and intersect with one another. 
In the middle is the power point called bindu, the invisible centre of everything. 
The triangles are surrounded by two rows of lotus petals 8 and 16. They represent creation and vital energy. The broken lines of the outer frame contain the four gates (or four directions).
Many positive aspects are associated with Shri Yantra. 

How to Use the Sri Yantra? Yantras as Meditation and Centering Device
It is widely believed that focus (and following meditation) on this Yantra will help attract abundance into your life. 
As you look at the Yantra, allow your eyes to focus on its central dot. This dot is called the “Bindu”, which represents the unity that underlies all the diversity of the physical world. Then, allow your eyes to see the triangles that enclose the Bindu. The downward pointing triangle represents the feminine creative power, while the upward facing triangle represents masculine energy.
Now, let your vision expand to include the circles outside of the triangles. They represent the cycles of cosmic rhythms. 
Bring your awareness to lotus petals outside the circle that point outwards. They symbolize the unfolding of our understanding. 
The lotus also represents the heart, the seat of the Self. When the heart opens, understanding comes.
The square at the outside of the yantra represents the world of form, the material world that our senses perceive and understand as separate. There are four T-shaped gates. They represent our earthly passage from the external and material to the internal and sacred.
Gaze at the center of the yantra. Without moving your eyes, gradually begin to expand your field of vision. Continue expanding your vision until you are taking in information from greater than 180 degrees. 
Now slowly reverse the process by re-focusing back to the center of the yantra. Now gently close your eyes. You may still see the yantra in your mind’s eye.
