The only letter to the lord Till when I have to hold the sword

I am a soldier I have no emotions
I left home to protect my nation
I killed many without knowing their names
I always move ahead leaving dead fames
The only letter to the  lord
Till when I have to hold the sword

I am a  Teacher I  have no pride
I build careers by taking same ride
I guide everyone to get them success
I always move ahead with no recess
The only letter to the lord
Till when I have to hold the sword

I am a leader I have no choice
I came out to raise mass voice
I walk on the road of  red flames
I always move ahead taking blames
The only letter to the lord
Till when I have to hold the sword

I am a Father I have no wish
I sacrificed everything for family bliss
I sold my dreams for grown up child
I always move ahead  but never cried
The only letter to the lord
Till when I have to hold the sword

I am a lord I give plights in life
I test everyone to make them survive
I read all letters with immense concentration
I give everyone a chance with no hesitation
The only letter to you and All
Learn to smile in pain and stand tall
