When I swing my brush quickly in the air, the ink splashes on the paper. When I lay down my brush, the ink slowly begins to spread on the paper. The spreading or splashing of ink are phenomena of nature. They are unexpected, and beyond the control of human hands. Even if they cannot be controlled, this is no reason to exclude them from my work; rather, I try to positively accept this, and complete my works together with the power of nature. In Japan, the word 'nature' indicates the whole of creation, including human beings. Humans are part of nature. I think what we have to consider now is not 'how we control nature for ourselves', but 'how we control ourselves for nature'.
