CIRCADIAN RHYTHMS

Evening heralds nightfall
Like thoughts before words;
Night begets morning
And not after its kind;
The sun rises and sets
Always from east to west;
Sleep forces my eyes shut
Holding captive my mind!
 
Daily repetitions
Are the rhythms of life
Each cycle pulsating
The beat of life’s great heart
The tick-tock of time’s clock
From Eternity’s past
Till Forever’s future.
