Analysis of Be cautious, my friend

O dear! Be cautious, be at ease
Don't think, I ‘m a fool
Who doesn't understand your tricks
To snatch and grab whatever you want
Be cool, cool, dear friend
But let me think whether you deserve
To be called a friend
I think you don't deserve it
You tried to play false and cheat
Now stop playing fast and loose with my feelings dear
Can't you see it brings much torment and torture?
Through your torrent shells of mortar
And evident foul dealings in love and care
Thus causing me a heavy loss
Of self respect, prestige and dignity
Yet you held your rigidity
And behaved like a boss
You a business tycoon
Don't forget the everlasting fact
That someday God will make you realize
He holds in His right hand
Men's rise and fall
So my dear friend!  Don't forget
God's  rule does not spare

Any act of deceit and cheat
