One thing that sets Empowering Pi apart from Empowering Pe or Empowering Ti is that the former is Creating while the latter are Accepting. As such the former relates to a very daring, dangerous (to the person him/herself) kind of activity, while the latter relates to something relatively safe.

I experience my own Accepting/Empowering function as something I do "because I can and might as well". It gives a very powerful kind of feeling and a sense of freedom and self-posession.

I think Empowering Pi is more immitatory than any Empowering Static function in some way... but I may be biased there.
