Zen Master Seung Sahn - The Spring Geese are Flying North

Zen talk:

True empty mind is before thinking. So thinking does not appear and does not disappear. This is the realm where nothing appears or disappears.

In the realm where nothing appears or disappears, there is no life and no death, no suffering and no happiness, no good and no bad, no you and no I. So it is said that all things in the universe return to the One.

But where does this One return?
