What is the difference in techniques for the invocatary &evocatary vibratory forumale?

I know that one vibrates the words so that your astral body vibrates along with it , which is the invocatary formuale while the evocatary formulae excites the atmosphere and also brings the unvierse to your senses and resonates in harmony to the vibration..

But the technique to do both is entirely the same. So , is the main difference the will on which one you wish to vibrate..for example , if you wish to vibrate the word within yourself , you target yourself , not outside?

The main thing that puzzles me that the technqiue to vibrate is the same..so , is simply the target different?

Also , Another question of mine is how would you know which words and which technique can be used? For example , in a ritual , and let's take the lesser Banishing ritual of the pentagram...you have to vibrate a variety of words..

So..how do you know which words to vibrate using evocatary formulae where you bring the universe in alignment and in harmony , or the invoctary forumale?

I am rather puzzled...can both serve and be used? Or when in doubt , can i vibrate it so that it boths invocates and evokes?
