Gosho Zenshu page 1568
Fish must have water, and birds depend upon
trees to build their nests in.
In the same way, for the Buddhas,
the Lotus Sutra is their source of life,
their sustenance and their dwelling.
As fish live in water,
so the Buddhas live in this sutra.
As birds dwell in trees,
so the Buddhas dwell in this sutra.
As the moon’s reflection lodges in the water,
so the Buddhas lodge in this sutra.
You should understand that in a land
where this sutra does not exist,
there can be no Buddhas.
