The doctrine was to pass these Homon (dharma-gate) and head toward 'Ken (exoteric), Esoteric and Ascetic standing trio' and perform 'Jugubodai Gegeshujo' (self-training and seeking Nirvana every day while looking up and converting others to the religion while looking down).
この法門をくぐり「顕・密・修験三道鼎立」を目指し、「上求菩提下化衆生」を行っていくと言う教義である。
