The traveler's eyes are opened. As they take their new found knowledge and glance back a mistake is noticed. Discomfort fills them up and makes them itch. They wish they would have not made that mistake and they know what the right action would have been.
Another fork in the path as appeared. Will they forget what they have learned so that they don't have to change? One path direction looks easy and goes down hill. It seems more comfortable and they know it well. The other path direction goes uphill and will require them to use their new found wisdom. It will take strength and determination to reject the old ways that resulted in mistakes. However wisdom is like the wind at your back when running. The push of the wind will get them to places that they haven't been before. It will provide strength to climb. Walking that uphill path with the strength of wisdom will bring them to a mountain top, a new view of the surrounding world.
To think it is just two forks in the path to a new perspective, right choices, and freedom from sin.
