OM is the whole universe coalesced into a single sound and represents the union of mind, body, and spirit.
The OM is made from cold rolled steel. It is cut with a plasma cutter, then designs are grinded into the metal and a dye or patina is applies for color. The piece is then sealed with a resin finish. It has a hook on the back for hanging.
It can be an indoor or outdoor piece if protected from the elements.
