An old pine tree preaches wisdom,

and a wild bird

is crying out truth.   

Anon 

You just have to be alert enough and you will find the whole nature is full of wisdom, and the whole existence is crying out truth from different sources. You just need open eyes, receptivity, sensitivity, awareness, and this whole existence becomes your home. Zen is concerned absolutely with your relaxation because only in relaxation does one sink deep enough into the original sources of life.

The whole existence becomes a totally different phenomenon the moment you disappear. Hence, you are the only problem. If you can dissolve your problem…it means you have to dissolve yourself. So there is no salvation for you, there is only dissolving yourself into the ultimate. And there is nothing greater, nothing more majestic, nothing more miraculous.
