Buddy's post is excellent.
the Five Element forms are not seen as techniques, but as Principles. If you see them as techniques, you could miss many ways to develop your practice.
For example, if someone see Pi Quan, they could say it's 'A palm strike'. And that's it.
Well, no.
Pi Quan trains your body to have the proper coordination/alignment/harmony to deliver force from up to down, no matter which 'star' you use (Head, palm, elbow, etc). That's why you see Pi Quan done with the head, the shoulders, the elbows, and many different variations; and as a strike, a jointlock, a throw, etc.
Same thing happens for all elements.-
