Purpose of Ardas - there are many versions and choice of words. Some giannis use the very short version, some add on relevant details and yet others add on even the irrelevant ones making it more impressive and long. So there is no one way about doing the purpose. I've also noticed that while doing the tan drusti di ardas, that part of the ardas isn't clearly detailed, often mumbled around and it's not eazy to catch the words spoken by the giani. Often the gianni softens his/her voice at this point.
But we can create our own choice of words, e.g. use Punjabi - English dictionary to get all the synonyms of "tan drust" and use all the key words in short sentences. This is the best way to have your own uniquely tailored ardas done.
