Yes masoud, I used "at all" and I was sure because I meant just in this certain sentence (کار آموزگار جاودانگی دارد).

Of course "daashtan" can be auxiliary verb somewheres!

:)

سلام آزالیتا

گفتم "آینده ی قشنگ" یعنی

The beautiful future.

"... correct my sentences immediately after sending my first comment."

or

"...correct my sentences immediately after I sent my first comment."

"In addition to my mistake about داشتن, I said that داشتن is not a transitive verb.
I was completely wrong."

say/ tell

In this case tell requires an indirect object: I told you.

"I did not care that an object can come without "را" either."
"When the object is unknown, so we remove را."

"... the third case is when an object describes ..." 

Please let me know if I have made any grammatical mistakes in either Persian or English.

suggestions

"daashtan" is not auxiliary verb at all. It is just a simple verb means "to have" (possession).

Azalea, you know the "Present Simple" should be used to describe obvious things as well as English.
