盧舎那仏(奈良の大仏)
Birushana Butsu, known in Sanskrit as Vairocana, is the cosmic Buddha understood in esoteric and Kegon Buddhist traditions to embody the totality of the universe and the source from which all other Buddhas emanate. In Japan this figure is most famously represented by the Great Buddha statues at Todai-ji in Nara and Kotoku-in in Kamakura, works that were historically tied to national protection and the consolidation of imperial and ancestral authority. Devotion to Birushana Butsu reflects themes of cosmic order and unity rather than specific worldly favors.
