One of my post was flagged.

I just saw one of my posts was flagged. I don't say it is wrong. Because it is very much in the interest of community development. But I just want to know the reason for flagging. In fact, I mentioned that it is not my own post and it is the daily class of some spiritual institution. So it should not be edited as per my view. I mentioned the referer also and also mentioned the full details of the same in my picture of the post. I will be highly obliged if anyone please guide me why it was flagged. Following is the link to that post. and also attaching the picture in which I mentioned the details of the classes conducted.
