Need help to correct grammar and sentence - gita

Would like help to find out the verse below from an unknown person's quote from Gita have the correct grammar

Why are you unnecessarily worrying? Whom do you fear? Who can kill you? Soul is not born, nor does it die.

What has happened has happened for the best. What is happening is happening for the best. What will happen will happen for the best. Do not brood over the past. Do not worry about the future. The present is on.

What have you lost, that you are weeping? What have you bought, that you have lost? What have you made, that have been destroyed? You bought not anything. What you have, you got from here. What was given, was given here. What you took, you took from this universe. What you gave, you gave unto this universe. You have come empty handed and shall go empty handed.. What is yours today was somebody else's in the past and will be somebody else's in the future. You think it is yours and are deeply engrossed in it. This attachment is the cause of all your sorrow.

Change is the Law of Life. What you call Death is Life itself. In a moment you are a millionaire in the very next you are a poorman. Mine-Yours; Small-Big; Ours-Theirs; Remove this from your mind, than everything is yours and you are everybodys'.

This body is not yours, nor you are of this body. Earth, Water, Air, Fire and Ether comprise this body and unto this shall it turn. But the soul is Immortal, then What are you?

Surrender unto the Lord, He is the Ultimate Support. He who experiences this is completely free from Fear, Worry and Despair.

Whatever you do, offer it unto Him. By this you shall forever experience Eternal Bliss.
