Hiroko Sakai said this quote
“ The more I drive myself into the depth of my inside, the more things come up to my vision, visibly or invisibly... I even do not know if I am seeing them with my eye or with my mind. I just need to copy them on my canvases. But this mental process is always overwhelming. I often have hard time to deal with my emotion on this state. You could call this depression on surface? But actually, so many 're-birth' and 'reform' are going on on my thoughts, inspiration, philosophy...etc in the underwater. I believe this struggle make my art real. My art always comes from my emotion. ”
