Mark A. Cádiz aka Rev. M. Seishin Cádiz

Artist Statement

I began drawing around the age of 4 or 5, after having nearly died from pneumonia.  When I came around, my mother brought me colored pencils, paper, and comic books to entertain myself. That was the beginning of my journey as an artist.  As I grew up, I used art to express feelings and perceptions that seem beyond language.  Art has provided me with a world without limitation.

Art is a creative meditation for me. To give form to a concept through my art is an expression of life. As long as I have the tools to liberate my creativity, I am free. Who we are is not limited to the perceptions of others or our physical form, nor can it be contained by them or by a piece of parchment framed by words. Art is my gateway to look beyond these seeming limitations to see true essence. 

My artwork has evolved and expanded to different mediums, subjects, content, and techniques over the years. Initially working with pencils, I began to develop my illustrative style. I incorporated new techniques acquired by mistake, by observation of other artists’ work, and through my exploration of a variety of genres. It wasn’t until I was in my early 50s that I began working with acrylics and watercolor. My style and technique are as diverse as my artwork: from the symbolic and metaphorical, to fantasy and the natural world. My art is influenced by my personal life experiences, the spiritual nature of reality, interconnection, and my musings.

Maybe something in my artwork will speak to and inspire someone else.
