Having studied the great Japanese and Chinese calligraphy masters of the 18th and 19th century, Hernandez decided to adhere to the traditionally Asian notion that philosophy and painting are one. For Eastern artists, the search for an understanding of the world and life is achieved through painting, expressing and reflecting the painter’s feeling emotions and experience. The painter strives for the True Gesture, the gesture through which he expresses his inner self.

After attaching himself to a calligraphy master and spending three years in a monastery in Japan learning calligraphy through repetitively copying characters until he was able to express his "true self" in the symbols. The intellect doesn’t direct anything in the creative process. The gesture just reveals itself.

The celebrated art critic Edorta Kortadi notes in the painter "a certain denial of the self enabling him to free himself in form and aesthetics. His work is radical, sober and deep, without any addition or references other than those of personal introspective or gesture methods. This is, we think, part of his achievement and main values."
