Resignation letter

Finally I got an opportunity to write one more resignation letter!!!.. Yes..I am leaving my current firm and going to be 'Berojgar' for next few days.
It has been a long time since I wrote my last resignation letter so I found it very difficult to write it. As usual first thing come in my mind was the mail I got long time back regarding 'World's smallest Resignation letter'. It is something like
Dear Sir,
f*** off. I am leaving.
But I have a very good relation with my manager; at least I think so, so I dropped the plan of electing it.
Then I went back on my last resignation letters. For those, who don't have any idea about my career path, my current firm is my 5th placement and for first 2 places, I hadn't submitted the resignation as there were policy of 'No last month pay' so I just run away after getting my salary credited to my account but after then I realized the need of relieving letters and work exp certificates, so I put my first resignation there.
It was a complete one page letter where I included multiple resignation letters, i got from Google.
I still remember the reaction of my Manager. He said that “Looks like you started it since you joined here. How did you get this much time to write this story?"
Well.. I was very happy at that time so I didn't react him but got the lesson that if your resignation is bigger than your appointment letter, it will make your manager unhappy!!!
Technically Appointment letter is antonym of Resignation letter but for managers, it is opposite of layoff.
It is same as saying" I quit!!" then listening "you are fired!!”
Anyways, I dropped to copy the same old letter and start a new Google search once again. While searching I realized that there is so much change comes in the materials available on net now a day. I still remember that my last time search, which was approx 5 years back, gave me 4-5 good letters on top. Now I saw that there are some 'Sponsored Links' coming in their place. I don't understand who sponsored the Resignation Letter and how they are running their business!! But it is none of my business so I moved to un-sponsored section of search and opened a few of them.
These letters were quite straight forward. I can say that it is not small as smallest resignation letter but they smell like them only so I rectified my search from 'Resignation Letter' to 'Polite Resignation letter' but I got the same results :(.
Then I thought an innovative idea and searched for 'Polite Resignation Letter for Indian Firm' and got some interesting results.
There was one post of an anonymous guy who wrote a story on which you can create a hit film. This was a story of poor family having father and mother suffering from bad health and this fellow has to take care of them so he want to relieved ASAP.
I rechecked the search subject and confirm I am still searching for polite and not emotional or Dramatic.
Any ways with some more permutation and combination, I got my final letter with search content as 'Polite Resignation Letter for an Indian Manager working in MNC' and finally I drafted my new resignation letter.
I am sending it to my manager and praying that I may get a problem free relieving.
