Waterwheel at Daio Wasabi farm in Azumino, Nagano, Japan. The farm appeared in Akira Kurosawa's film, Dreams (1990; see film clip, below, and my previous posts on that film, here, here, and here). Image Source: Youtube.
Is time a circle? Sometimes, it looks as though the wheel turns and returns. The wheel of fortune represents two opposing things: a divination of the future, or luck at the roulette table. That means the wheel, which is also a symbol of human technology, mixes a message about the passage of time because it combines order with chaos. The wheel supposedly reveals the points where Fate meets Fortune. Looking at a problem linearly, we might believe the past is gone, done and fixed, indicating the path of future destiny. But if time is a circle, we can revisit the past, gamble again and change its story.
