O Good Man

“O good man! Compassion acts as a parent to all beings.
The parent is compassion.
Know that compassion is the Tathagata.
O good man! Compassion is the Buddha Nature of all beings.
Such a Buddha Nature is long overshadowed by illusion.
That is why beings cannot see.
The Buddha Nature is Compassion.
Compassion is the Tathagata.”
