Sahasrara is the seventh chakra in yogic tradition and it is represented by the thousand-petaled lotus. Sahasrara is located above the crown of the head and it is the connection to pure consciousness. Our Sahasrara Mat will bring forth a sense of oneness and unity. Sustainability Cork is the outer bark of the Oak Tree. The Oak tree is never cut down to harvest cork, rather the bark is stripped by hand! No part of the bark is wasted during cork production. Oak trees regenerate their bark by absorbing five times more Carbon Dioxide than an oak tree that hasn't been harvested. The other side of the mat is made with sustainably harvested tree rubber from rubber trees, a renewable resource. These mats don't contain any PVC, EVA or synthetic rubber making your mat both kind to you and kind to the earth. All designs are made using water based inks to avoid chemicals The best thing: They come from the earth, they go back into the earth! The mat is 100% biodegradable, so by buying it you aren't increasing your carbon footprint.
