Everything has a frequency.  Visible objects have a frequency as do inner states, which are not visible.  What does the frequency of anger feel like?  What does the frequency of joy feel like?

Inner states may lead to actions or they may not.  Actions are, of course, important and there should be harmony between inner state and outer actions.  However, your inner state comes first.  It is the most important.  It is the point of power; the pivot of creation.
