The pilgrims’ hymn for Shōhōji Temple (正法寺), more familiarly known as Iwamadera Temple (岩間寺), from a hymnal for the thirty-three temples of the western pilgrimage circuit dedicated to Kannon Bodhisattva (観音菩薩)
My own rough, tentative translation follows:
Number Twelve: Mount Iwama Shōhōji Temple (Shingon school) in Shiga District, Ōmi Province
Ishiyamauchi Hata, Ōtsu City, Shiga Prefecture
A hymn for Thousand-Armed Kannon:
If seeking the source
Of the stream, over by the
Temple amongst cliffs
Waves rushing past riverbanks
Sound like wind amidst the pines
