“When we see something we recognize in the phenomenal world, like a cloud, we say it is there, it exists. And when we can no longer see it, we say it is not there, it no longer exists. But the underlying truth is that it still exists, even if its appearance has changed. The challenge is to recognize that thing in its new forms. This is the meditation on signlessness.” – Thich Nhat Hanh, The Art of Living
