It points out the struggle of life in terms of a journey we must all make.
The journey can never be free of worry or responsibility although we will have oasises
to refresh us when things become too much to bear.
The beauty of the poem is we are never alone in our struggles and as we look around we see others making their way through life overcoming similar circumstances .
In the end we will find rest , and interestingly it could be a religious entry into heaven or just a peaceful cessation of life’s struggles.
