Sōseki Natsume said this quote

Knowing that it is the earth we tread, we learn to tread carefully, lest it be rent open. Realizing that it is the heavens that hang above us, we come to fear the echoing thunderbolt. The world demands that we battle with others for the sake of our own reputation, and so we undergo the sufferings bred of illusion. While we live in this world with its daily business, forced to walk the tightrope of profit and loss, true love is an empty thing, and the wealth before our eyes mere dust.
