Some Primary Aspects
In its original significance the torii was not merely a decorative gateway. It was a magical, protective device which guarded the opening in the shrine fence against the entrance of evil and contamination of all sorts. Sometimes the approach to the shrine is made through a first, or outer, torii, then through a second, and finally a third. Occasionally one meets with an extended series of torii set so close together as to make a veritable tunnel.
