Dogen-zenji said, “Although everything has Buddha nature, we love flowers, and we do not care for weeds.” This is true of human nature. But that we attached to some beauty is itself Buddha’s activity. That we do not care for weeds is also Buddha’s activity. We should know that. If you know that, it is all right to attach to something. If it is Buddha’s attachment, that is non-attachment. So in love there should be hate, or non-attachment. And in hate there should be love, or acceptance. Love and hate are one thing. We should not attach to love alone. We should accept hate. We should accept weeds, despite how we feel about them. If you do not care for them, do not love them; if you love them, then love them.
Dogen said, “A flower falls, even though we love it; and a weed grows, even though we do not love it.” Even though it is so, this is our life.
