Okay. Now I understand the problem. You are essentially using a different word, although it is spelled in the same manner.
The word content, within the context I used it in my article, was an adjective. This adjective means a state of peaceful happiness, which if anything is even better than happiness in itself.
You are referring to the verb content. That's a completely different word with an entirely different meaning. That word means, "to settle for less," to put it in simple terms.
It's like if you went to a bar and wanted some Jack Daniel's, but the bartender told you there is none left. You would then content yourself by ordering a Captain Morgan's instead. You're happy with it, but it's not what you initially wanted.
I hope this clarifies things.
Edit: I just read the end of your comment and I must inform you, that once again you are incorrect.
to say someone that is in a state of contentment is blissfully happy is wrong.
The word contentment is tied to the noun content, not the verb, and thus, it means exactly what you think it does not.
