What Is The Word Doctor?

What is the word "doctor"?

When I hear the word doctor

I remember, civil war

Between devil and God,

The smell of that white 

Sanitized floor,

Almighty victorious soldier

Without even a sword,

Someone challenged 

Impermanence,

The idol of humanities preference,

A magical wand,

Reason of mother and child bond,

Not a duty, a responsibility,

Million prayers for a single operation,

Medical missions of uncertainty,

Million smiles for every succession,

Music of many heartbeats,

Unfortunate noise of beep,

The hope of about to die one,

Busy schedule, maintained discipline,

Nightmares of severe disease,

Hard work until I could say scalpel, please!
