I would just like to thank Bhai Kulbir Singh Jee for taking the time to write this article. It was very badly needed. I did learn a lot of new things from this that I had no knowledge of before. With Guru's kirpa I always made an effort to say the Mangalacharn before, this article has just made my beliefs even stronger. I have till date not come across a good argument by those veers who say why some places Mangals should not be read first other than so and so Mahpursh said so.
As for whether the Bhagats wrote Mangals or not that is a different issue from the topic of this thread, whether or not they wrote it we can still agree that Mangal should still be read first.
