I walk this passage of three certainties

There is no turning back.
The fog's blanket is eternal.
Only the next step can be seen.

Not all doors unlock with a set of keys

One foot stalks the other.
Only to reach a sign of fate.
Dead End never seemed so serene.

Change replaces fog as it lifts with ease

The road forks left and right.
The next step grows but which one ends.
Seems two roads I must choose between.

Not all that is certain appears in threes
