The 'white" series is an ongoing body of works. Mullen is interested in bringing together two concepts of emptiness seen from the Eastern and Western conflicting perspectives. Pure white as Western experience of absolute Nothingness and the raw linen as the Eastern universal approach of a holistic positive sense of being in emptiness. By bringing the absoluteness of the whiteness and the raw linen, Daniel Mullen is looking for a way to harmonize these two opposing perspectives on emptiness/nothingness together.
