How does Jason avoid the curse that waits anyone who sees the herons ghost?

Jason avoids the curse associated with seeing the heron's ghost by cleverly using a mirror. When he encounters the ghost, he reflects its image back at it, thus preventing himself from directly viewing the apparition. This clever maneuver allows him to escape the fate that befalls others who gaze upon the ghost. As a result, he remains unharmed and able to continue his journey.
