I believe it is possible to insert the early Wittgenstein into a tradition of authors that we can generally classifyied as a form of negative theology. One of my favorite authors of this tradition is Pseudo-Dionysius the Areopagite. In his work The Mystical Theology, Pseudo-Dionysius writes about a Silence, beyond all that can be known, in which resides what highest and absolute. This Silence would be like a light that is so luminous that it reveals itself to us as a darkness, accessible only to those who know how to close their eyes.
In meditation we can find the experience of this ineffable silence. There is a moment in the practice of meditation in which words cease. The attempt to express this photographically is recurrent in my visual research. It is this search that led me to the works of OM.
