Emptiness is Full of Impermanent Existence (poem)

Emptiness is empty of nothing,
for nothingness is empty of
nothing, and the void is full
of emptiness, that freedom
from permanence and non-existence.
Thus emptiness is empty of
permanence, and of non-existence.
He who is certain of this
understands Buddhist logic,
and his mind is empty of
the confusion called doubt.
