Shōbō-genzō: Genjō Kōan (Actualizing the Koan): - Dōgen

The many rivers which flow into the ocean become the one taste of the ocean; when they flow into the pure ocean of the dharma there are no such distinctions as delicacies or plain food, there is just one taste, and it is the buddhadharma, the world itself as it is. In cultivating the germ of aspiration to live out the Way, as well as in practicing the dharma, delicious and ordinary tastes are the same and not two. There is an old saying, “The mouth of a monk is like an oven.”45 Remember this well.

Right and wrong are temporal, but time is neither right nor wrong. Right and wrong are the Dharma, but the Dharma is neither right nor wrong. In the balance of the Dharma, wrong is balanced. In the balance of the Dharma, right is balanced. And so, in learning of complete and utter Awakening, in hearing the Teachings, doing the training, and realizing the effect, this is profound, vast, and wonderful. Some hear of unsurpassed Awakening from good friends, and some hear of it from the sutras. What one hears first is, "Not doing wrong action." If one does not hear “not doing wrong action,” one is not hearing the Buddhas' true Dharma but demonic talk. Know that hearing “not doing wrong action” is hearing the Buddhas' true Dharma.

"Kind speech" means that when you see sentient beings, you arouse the heart of compassion and offer words of loving care. It is contrary to cruel or violent speech.
