This large Mandala is presumed to be have made for Reverend Nichiro; one of Sage Nichiren's Six Major Disciples. It is called the Rinbo or Chakraratna because of the pattern of the scroll on which it is mounted. If I read correctly, the Chakra Jewel may have been Nichiro's family crest, but do not bet the farm on that.
