take its course

Let it happen

When something takes its course, it proceeds naturally without interference until it reaches its conclusion.

The phrase implies that events have their own momentum and timeline that shouldn't be rushed or manipulated.

Let the illness take its course suggests allowing a condition to progress through its natural stages.

The expression often carries a sense of resigned acceptance—that some processes simply need time to unfold on their own.
