When you turn dull
When you do not want to live any longer
When you invoke death as your last refuge
When you do not have any initiative
One minute past You do not long for death as well
You can move with the Earths diurnal motion
And dance in chiaroscuro night and day
And learn the fun of life and death
Dr. Ramesh Chandra Mukhopadhyaya
