If we seek the Buddha outside the mind, the Buddha changes into a devil.

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.

Coming, going, the waterbirds, don't leave a trace, don't follow a path.

That you carry yourself forward and experience the myriad things is delusion. That the myriad things come forward and experience themselves is awakening

Through one word, or seven words, or three times five, even if you investigate thoroughly myriad forms, nothing can be depended upon. Night advances, the moon glows and falls into the ocean. The black dragon jewel you have been searching for, is everywhere.

But do not ask me where I am going, As I travel in this limitless world, Where every step I take is my home.

The one and only thing required is to free oneself from the bondage of mind and body alike, putting the Buddha's own seal upon yourself. 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.
