The symbol of the lotus (Sanskrit: padma) primarily represents untouched beauty and non-attachment. The lotus is rooted in the mud but floats on the water without becoming wet or muddy. This symbolizes how how one should live in the world in order to gain release from rebirth: without attachment to one's surroundings.
