। ॥ ४५३ ॥
In plain words
An arrow shot in the belief 'that's a tiger!' doesn't suddenly stop mid-flight just because it becomes clear, too late, that it was only a cow. It goes on and strikes anyway, with everything it had.
Close to the Sanskrit
An arrow released under the thought 'it is a tiger' does not, afterward, stop even when the cognition 'it is a cow' arises — it pierces the target with full, unrestrained force.
