The statue arrangements at Taisekeji

  "The Three Treasures of the Buddha, the Law and the 
  Priest are one.  This is clear if one examines the way 
  in which the True Object of Worship, the Gohonzon, is 
  enshrined in this sect.  At many local temples, for 
  example, the Gohonzon are enshrined in the 'Three 
  Treasures Within One Body' mode, in which we pray to the 
  three treasures embodied within one Gohonzon. Yet, at 
  the Miedo (Image Hall) at the Head Temple, the staue of 
  the Daishonin is enshrined in front of the Gohonzon. 
  Nonetheless, even though the Person and the Law are 
  separate, each carries the significance of the 'Three 
  Treasures Within One Body'.  Further, within such temple 
  structures as the Grand Reception Hall at the Head 
  Temple, when one faces the Gohonzon, to the left, there 
  is an enshrined statue of the Daishonin, and to the 
  right, one of Nikko Shonin.  In this way, WE ARE ABLE TO 
  OFFER OUR PRAYER TO EACH TREASURE INDIVIDUALLY. 
  Although this form is entitled 'The 3 treasures in 
  Separate Bodies', because they are enshrined in a 
  trinity,THEY FORM A SINGLE GOHONZON.  It therefore 
  follows that the treasure of the priest is to be 
  ragarded with as much reverence as the Treasure of the 
  Buddha and the Treasure of the Law."  (pp11-12
