I don't think His Holliness is trying to unite all Buddhism school into one. The reason why there are thousands over Buddha teachings for us to learn is because each of us has different characters, learning skills, preference, habituation etc and with so many approaches, there must be one teaching suits you.
As long as we have strong faith in the three Jewel, be loyal to your guru, transform yourself to be better, clearly understand the law of cause and effect and it prohibited you from doing bad things because you know karma comes back. Be selfless and serve dharma all the way. No matter what religion your are or even a free thinker, at the very least, just be a kind, compassionate and selfless person. Of course, with the help of spirituality, is a bonus. Do not let the ban or whatever political controversy going on out there stop you from having faith with your own belief.
