Wujifa is a principle based (or the reason we say "fa" in Wuji-fa) practice where connections are noticed and develop in many different ways. The methods use in the practice of Wujifa are as we say "not the truth" to what Wujifa is or can become with training. Although we say "methods" are like medicine and can help one understand more directly the aim of this practice like the finger pointing toward the moon it is not the methods that are important as the outcome of connecting with the deeper meanings and understanding. Since people can have many different levels at which they understand so by doing one method it may not be as useful as another method could be and so the willingness to explore, verify, and notice ones own progress is very important.
