Mountains and waters right now are the actualization of the ancient Buddha way. Each, abiding in its phenomenal expression, realizes completeness. Because mountains and waters have been active since before the Empty Eon, they are alive at this moment. Because they have been the self since before form arose they are emancipation realization.

Because mountains are high and broad, the way of riding the clouds is always reached in the mountains; the inconceivable power of soaring in the wind comes freely from the mountains. 
Eihei Dogen Zenji

These Sierra mountains
Are not the true mountains
Beneath these untrue mountains are the rivers of delusion
Which, by the way, are just fine for traveling home
Doen
