The Oxford dictionary definition of tunnel is as follows:
- An artificial underground passage, especially one built through a hill or under a building, road, or river.
‘a road tunnel through the Pyrenees’
‘the Mersey tunnel’
A tunnel is, by definition, a passage. A tunnel is a means for moving through or past something. A tunnel is a device, if you will, that has been implemented to get from one place to another; or from one situation to another. A tunnel represents progress, it represents a transition, a movement, a change of state or mind or place. And change means that if you persevere, things will be different. Things will not remain the way they are. They never do, because change is an inherent part of our lives. So maybe life won’t always be a walk in the park; sometimes it’ll be a walk in the dark but that doesn’t mean that darkness is the ultimate constituent of your life. Maybe it just means you’re going through a tunnel with poor lighting.
There is always a light at the end of the tunnel.
