"賽は投げられた"

Simplified Meaning:

When someone says 'the die is cast,' it means that a decision has been made and there's no turning back. Imagine you are playing a board game with dice. Once you roll the dice, you can't change how they land; you have to accept the outcome and move forward. This phrase means that a choice has been made that can't be undone. For example, when you decide to quit your job to start your own business, you are taking a big step that will change your life. You've made a choice, so now you have to deal with whatever happens next, whether it's success or challenges. This idea comes from history too. Julius Caesar, a famous Roman leader, used it when he crossed a river with his army, knowing it would lead to a major conflict. By crossing the river, he made a decision that he couldn't undo. In everyday life, if you choose to study hard for a big exam, you've committed to that decision. You can't go back and undo the effort you've put in; you just have to see it through and take the exam. So, 'the die is cast' is about accepting that a decision or action has put you on a certain path, and you have to see where it leads.
