What is located in the center is 'the central eight-Petal Court' and Taizokai Dainichi Nyorai (who is in a posture of 'Hokkai Join' (Dharma-realm meditation mudra) folding both hands in front of the belly) is sitting on the center of a lotus flower with 8 petals.
その中心に位置するのが「中台八葉院」であり、8枚の花弁をもつ蓮の花の中央に胎蔵界大日如来（腹前で両手を組む「法界定印」を結ぶ）が位置する。
