What is a Yantra?
Yantra's consist of geometric symbols, and are bleived to hold certain vibrations. Sometimes they are also connected to a diety. They have been used for thousands of years by tantra masters, yogi, and hindu practitioners.
How do you use a yantra? Focus on the center point, and let the rest of the peice dissolve into the background. You might find that the yantra vibrates.
I have chose to combine these powerful symbols with flowers and nature, as I find they are all connected.
