Twelve new yantras have been added to The Art of Yantras collection, where the whole "yantra" thing is explained. These originally appeared earlier this year as Daily Doodles, but in these images, the Doodle lettering has been swept off, the yantras are more extensive and images displayed on the page are slightly larger, and slightly sharper (PNGs instead of the Doodle JPGs). A larger (2000x2000) version is available.

Go to the The Art of Yantras page or start with the first of the new images,
Seraphic Host.
