Life and death are nothing but the mind. Years, months, days, and hours are nothing but the mind. Dreams, illusions, and mirages are nothing but the mind. The bubbles of water and the flames of fire are nothing but the mind. The flowers of the spring and the moon of the autumn are nothing but the mind. Confusions and dangers are nothing but the mind.

If you do this as you sit in ecstatic meditation, the whole universe itself scattered through the infinity of space turns into enlightenment. This is what I mean by the Buddha's seal.
