This quote by Thomas Merton can not be any truer. For artists, before they could find meaning in their artwork, they first lose themselves in the process, they lose grounds of the reality to create a world of their own where they discover more about themselves.
And for observers, this is also true. How many times have you looked at an artwork and find yourself confused? And if you stare long enough, you begin to interpret its meaning that is uniquely your own.
