A sanmon's size is an indicator of the Zen temple's status. Structurally, the sanmon of a first rank temple as Nanzen-ji in Kyoto is a two-storied, 5x2 bay, three entrance gate (see photo below). Its three gates are called kūmon(空門gate of emptiness), musōmon(無相門gate of formlessness) and muganmon(無願門gate of inaction) and symbolize the three gates to enlightenment, or satori.. Entering, one can symbolically free him or herself from the three passions of ton(貪greed), shin(瞋hatred), and chi(癡foolishness). A third rank temple will have a single-storied, lx2-bay, single entrance gate.
