The Odaimoku お題目 chant – repeating the title of the Lotus Sutra Namumyohourengekyou 南無妙法蓮華経 – is principally associated with the Nichiren-shu school but was originally part of a Tendai chant, the school in which Dogen Zenji grew up with.
Here I am walking in a quiet Glasgow park whilst chanting, at a fairly slow pace so I’m not too much out of breath! We have been chanting it in our Chanting Group recently online.
